Mathematis – iPhone App Giveaway

MATHS INSIDERS bloggs (8)

Mathematis is a universal educational app for iPhone that helps speed up kids addition, subtraction, multiplication and division??.

With a bright aliens and space theme, set on the faraway planet of Mathematis, your child has to save the peaceful Mathematians from the bombs of their evil nemeses, the Innumerators, by solving math problems. For every math question solved correctly, a Mathematian’s spaceship escapes their war-torn planet; get a question wrong, and the ship is grounded.

The game is suitable for kids aged 4+ and has customized settings so that your child can play at their correct level whatever their age. For young kids, set a low limit on the answer range to make sure they’re getting easy question. Increase the limit as your child’s skills improve.

I really like the game’s bright graphics and the built in “Do Over” mode which let’s kids have another go at questions they skipped or got wrong. There’s also a parent page where you can track your child’s progress.

mathematis

Mathematis is a great app for practising arithmetic skills. It doesn’t teach kids how to work out the answers, so is best used as an app to reinforce and improve your child’s mental math recall. The audio on the game is also really loud, and you’ll need to go into your phone’s settings to make it quieter, which isn’t so great for us parents with sensitive ears, but the developer assures me he’ll make the sound adjustable in the next update!

Maths Insider is giving away 3 free app store codes for Mathematis. To grab your free coupon code for Mathematis, email me at caroline@mathsinsider.com with the subject line “I want Mathematis”

I’ll pick 3 people at random after 9am GMT Wednesday 12th June 2013.  

Competition now closed. Congratulations to Ada, Chloe and Maryam who won a free app store code each for Mathematis!

MATHS INSIDERS bloggs (10)

When it comes to the times tables there are lots of different ways of learning them – through songs, videos, board games and of course, through tablet apps. The key to speedy stress free learning is to practise them often until they become fixed in your child’s head, like the names of all the characters in Phineas and Ferb or the latest One Direction lyrics. For the iPad generation, a few minutes a day on a times tables app could be all they need to fix the multiplication facts in their heads.

Check out the guest post by Ken Myers below to find out the latest and coolest times tables apps for the iPad to help your child crush their times tables:

 This is a guest post by Ken Myers

When using an iPad, children would rather be entertained than be faced with grueling schoolwork. Although tablets are a tool, children see them more as a fun, touch-screen device that connects them to a variety of entertainment. Why not give them what they seek while providing an education? If they can be engaged on an educational level without it seeming like it’s related to school, there’s a far better chance that the iPad can be used for more than just watching movies and playing games.

Listen Up! 8 Fascinating Podcasts to Spark a Love of Math in your Teen

MATHS INSIDERS bloggs (11)

I’ve calculated that I spend around 14 hours a week in my car, with school runs, and shipping my kids to after school activities. During these trips, we spend a lot of time chatting (If you could live anywhere in the world, where would you live?) and also a little time  staring at the traffic out of the window as well as a lot of time bickering.

One of my favorite in-car activities when I’m on my own in the car is listening to podcasts. I’ve even spent a few dollars and bought the amazing Downcast app so I can easily search, arrange, queue, and play my favorite podcasts. It’s way better than the built in podcast app on my iPhone and is well worth the $1.99.

As well as the Freakonomics podcast which almost always gets played as soon as it’s released and is popular with my teen and preteen as well, we also love the How to Do Everything podcast. I’ve only been listening intensively to podcasts for the past few months and as with any new hobby, I can’t help thinking, “Everyone should be doing this!”

Listening to podcasts is a great way of taking in new information and taking a fresh look at old information for anyone with a busy lifestyle, like parents and teens. So whether you’re a fellow podcast fan or have yet to discover this cool way of filling in dead time; here’s a list of 8 fascinating podcasts to help spark a love of math in your teen:

Podcast

Freakonomics Radio

In their books “Freakonomics” and “SuperFreakonomics,” Steven D. Levitt and Stephen J. Dubner explore “the hidden side of everything,” with stories about cheating schoolteachers, self-dealing real-estate agents, and crack-selling mama’s boys. The Freakonomics Radio podcast, hosted by Dubner, carries on that tradition with weekly episodes. Prepare to be enlightened, engaged, perhaps enraged, and definitely surprised.

This is my favorite podcast of all. The mix of statistics and economics and psychology brought to life by the 2 Steve’s makes this a must listen-to podcast series. Episodes range from just a few minutes long to up to an hour, but the professional editing and storytellinh=g makes those minutes whizz through in a flash.

Maths Insider pick: Women Are Not Men

Equality of the sexes has long been a goal, and in many ways that goal is being met. But, as you’ll hear on this program, the variance between men and women on some dimensions is still large. … We’re not trying to start any arguments. We’re just trying to look at the data that show differences between men and women to figure out why those differences exist, and how meaningful they are.

Math Dude Quick and Dirty Tips

The Math Dude’s Quick and Dirty Tips to Make Math Easier seeks to undo those years of classroom pain and suffering. Find tips and tricks to make math fun—and useful—again.

Part of the Quick and Dirty Tips team which includes my other favorites, The Get Fit Guy and The Mighty Mommy, The Math Dude unravels the mysteries of math in these short podcasts. (each episode is usually less than 10 minutes long)As a teacher and mathematician Jason Marshall holds the listener’s hand as he cuts through the math jargon.

Maths Insider pick: How to Use Percentages to Easily Calculate Tips

Learn the power of ten percent to easily calculate the tip next time you visit your favorite restaurant.

More or Less: Behind the Stats

Tim Harford investigates numbers in the news. Numbers are used in every area of public debate. But are they always reliable? Tim and the More or Less team try to make sense of the statistics which surround us.

More or Less is another podcast which I love listening to with my 13 and 12 year olds. It’s made by the BBC which as an expat Brit reminds me of home. Highlighting the way in which math and statistics can be used and misused, each episode will leave you with a great talking point as to why the statistics you’ve heard recently in the news may not be all they seem.

Maths Insider pick: Are there more black men in college or prison in the US?

Only last week Ivory Toldson heard the speaker say there are more black men in prison in America than in college. ‘Here we go again’ he thought. Only the week before he had written his second article on why this statistic is not true. This week Ruth Alexander looks at where this ‘fact’ came from and why it is still being used.

Math Mutation

Welcome to Math Mutation, a podcast where we discuss fun, interesting, or just plain wierd corners of mathematics that you would not have heard in school.

I only came across this podcast while rearching this post, but it’s such a nice little podcast that I’ve added it to my Downcast podcast list. An independent podcast presented by engineer and teacher, Erik Seligman, these 5 minute podcast episodes are a mix and myth-busting and math, with some jokes thrown in.

Maths Insider pick: Perfect Maps

The various complications in creating 1 to 1 scale maps.

perfect maps podcast episode

Travels in a Mathematical World

Travels in a Mathematical World is a mathematics (or maths or math, if you like) podcast by Peter Rowlett, Institute of Mathematics and its Applications, featuring mathematicians talking about their work as well as features on maths history and maths news.

Peter Rowlett has taken a break from making these podcasts for the time being, but there’s plenty of cool episodes in the back catalogue to entertain anyone with even a small amount of interest in mathematics. I really like the short interviews with real-life mathematicians explaining how they use math in their careers.

Maths Insider pick: Interview with Sarah Norton – Systems Engineer

Sarah Norton talks about her work in systems engineering and a specific application for fire engines responding to mobile phone emergency calls.

Inspired by Math!

As the blogger at Wild About Math! Sol Lederman interviews people who are inspired by math and are inspiring others.

When I first started Maths Insider nearly 3 years ago, Sol Lederman was kind enough to publish my guest post (Sneaking Math Into Children’s Diets) on his wildly popular Wild About Math! blog. Sol interviews a variety of folks who in one way or another are helping to dispel the idea that math is a difficult and boring subject.

Maths Insider pick: Leila Schneps & Coralie Colmez

An interview with the mother-daughter team who authored “Math on Trial: How Numbers Get Used and Abused in the Courtroom.”  Talking about inspiration for writing the book, flaws in mathematical thinking, how justice is derailed by bad math in the courtroom, a number of examples of cases from the book, and more.

Pop-Up Economics

Economist Tim Harford weaves together economic ideas with some remarkable personal histories, telling short stories about fascinating people in front of a live audience in some unusual locations.

Another cool BBC podcast, this time linking math, economics and really interesting storytelling. These 10 minute episodes are great for teens and adults alike as the relate how individuals have made use of math to achieve some fascinating results.

Maths Insider pick: The day the geeks took over poker 

The story of Chris Ferguson who applied game theory to poker and won. Big time. But, as Ferguson would find out, there’s always a bigger game.

A Brief History of Maths

Professor Marcus du Sautoy argues that mathematics is the driving force behind modern science. Ten fifteen minute podcasts that reveal the personalities behind the calculations from Newton to the present day. How do these masters of abstraction find a role in the real world?

These stand alone episodes  take a peak inside the lives of some of the most notable mathematicians through history. Sit back and listen to Professor Marcus du Sautoy and his guests tell the stories behind these famous mathematicians including how they started on their path to math greatness and how they overcame the obstacles they faced.

Maths Insider pick: Evariste Galois

Professor Marcus du Sautoy on his favourite mathematician, an angry, young genius who did his best maths in prison and died in a duel, aged 20.

Why Kids Should Care About Math: 3 Unlikely Careers that Use Math Skills

MATHS INSIDERS bloggs (1)

This is a guest post by Susan Cumberland, owner of School is Easy Tutoring in Vancouver

Not all careers require extensive math study, however, most careers do utilize basic math skills everyday.

If your child doesn’t care about math and wonders why it is important for them to learn math at school or with a tutor, here are 3 unlikely professions that use math skills that could help your child start to care about math. After reading this, they just might be motivated to learn after all.

Maybe your child wants to be a fashion designer, a chef, or a racecar driver? They will be surprised to see that these three professions use math all the time.

Math for the fashion designer:

Fashion design math

Anyone who has ever done a sewing project knows how important measurements are. Without the proper measurements or with the slightest inconsistency, the finished product will not fit properly or will look poorly made. When designing a garment you have to take into account the width of the seams and make sure you cut enough fabric to allot for the seams, so that it is the perfect size once it is all sewn together.

If your child fantasizes about becoming a famous fashion designer consider doing a sewing project together. Let them learn just how important the proper calculations are. First you need to calculate how much fabric you will need for your project. Fabric is measured in yards, so they need to know how many feet or meters are in a yard. Then they will need to take measurements of the person or the mannequin to determine the final size of the garment. Then they need to add 5/8” to each side of each piece of material for the seam allowance.

If they are impatient and just want to do the project without calculating, then let them try and see how it turns out. Once they see that the final product doesn’t fit or they don’t even have enough material to finish their project, then they will truly value the importance of math.

Math for the chef:

chef math

Whether you are restaurant chef, a pastry chef or an at home cook you will find that math skills are very useful in the kitchen.  When buying ingredients you need to calculate how much of each ingredient you will need and how much it will cost. For a pastry chef in a bakery, if someone calls in an order for 500 cupcakes, you need to know how much extra flour, sugar, eggs etc. you will need in order to make 500 additional cupcakes.

You also need to calculate how many batches of cupcakes there will be and how many ovens you have, in order to determine how long it will take to bake all of the cupcakes. These math skills are all important so you can have the order ready in time for the customer to pick up.

To emphasize the importance of math for your child who wants to be a chef, why not let them plan a special dinner for friends and family. When cooking or baking for a larger group of people, recipes need to be adjusted. Your child will need to learn how to double a recipe (multiply 2/3 of a cup by 2 to get 1 1/3 cups) or convert from grams to ounces and pounds.

They should establish a budget for the meal.  If they invite five guests, then they need to calculate how much of each ingredient is needed for each item of the meal. Help them to do the calculations on a piece of paper and then make a grocery list with the final item quantities and prices.

Once they go to the grocery store they will have to figure out what adjustments will need to be made in order to prepare the dinner within their budget. They could also prepare a menu with the meal prices so they can see how much of a profit would be made after subtracting the cost to prepare the meal. As a bonus question they could also calculate the tip that guests would need to pay the server.

Math for the race car driver:

Ford Fiesta RS WRC (2011)

Race car driving doesn’t seem like a career that utilizes math. However, race car drivers are constantly doing mental math, even when they are in motion on the racetrack.  A race car driver needs to be able to calculate their speed in relation to the degree of the curve in the race track in order to know how much to slow down and how much to turn the wheel. These calculations are necessary in order for the driver to maintain their lead in the race and also to ensure their own safety.

They also need to calculate how much gas is being used while driving certain speeds so they will know how many gallons are left in their tank and when they need to take a pit stop to refill the gas tank. Using this type of math keeps race car drivers safe, prevents the car from running out of gas in the middle of a race and helps them win first place.  Who knew that math would be so useful for a race car driver?

The book How Race Car Drivers Use Math? is for students who are between the ages of 7 and 11.  It shows how race car drivers use math as an everyday tool.

These are just three unlikely careers that use math, but there are many more.  Whatever career goal your child has, there are ways to show them the importance of using math skills for those types of jobs as well.  Your child may even have fun during the learning process!

The Ultimate Kumon Review Without the Kindle Worry

MATHS INSIDERS bloggs (3)

Yesterday was a busy day.

At the start of the day, I knew I had to drop my 4 kids at 2 different schools 20-rush-hour-traffic-on-the-highway-minutes apart from each other. But that was usual for a Monday morning, and although the school bus would normally be kind enough to drop the older 2 home, I knew that my daughter really wanted to play in her soccer match another 15 -rush-hour-traffic-on-the-highway-minutes, after school, with all the younger kids in tow.

I was mentally prepared.

Except when aforemenentioned daughter announces half way into our 20-rush-hour-traffic-on-the-highway-minutes journey, that she left her Chemistry book at home and REALLY needs it. Well there’s no turning back, and since she had the good grace to bring home an A in Chemistry in her mid year school report last week, I silently wept as I mentally crossed off an hour of “me time” from my morning calendar.

The 3 different times for the afternoon pick up went well and I even managed to deprive my kids of Mr HotDog by quickly throwing together a chicken pasta bake for them to eat out of plastic containers in the car on the 15 -rush-hour-traffic-on-the-highway-minutes after school journey t0 the soccer pitch.

I survived the day, her team won the match, and we got home in time to get the little two to bed at a later, but still decent hour. But it wasn’t the kind of day where I would have had time to sit down and research the family holiday, or how to support my kids weaknesses, or do a workout or any of the other gazillion things that busy parents need to do.

And I know that a lot of parents want to buy The Ultimate Kumon Review but don’t have the Kindle App on their iPhone, Android phone, tablet, or computer and were having one of those day’s, week’s, year’s where it just was not going to happen.

So since today is a much quieter day, I’ve finally put The Ultimate Kumon Review for sale as a PDF copy that you can read instantly (or save it for later) on any device. It’s exactly the same as the Kindle version and it costs the same $2.99 (or whatever that converts to in your currency). Here’s a screenshot of what one amazon customer had to say about the book.

Screen Shot 2013-03-14 at 7.02.58 PM

If you want to join the over 400 people (yes, I also finally got round to totalling my sales as well) who’ve used The Ultimate Kumon Review to help them decide if the Kumon program is right for their child, then of course you can still click through to buy the Kindle version on the Amazon.com Kindle Bookstore or the Amazon.co.uk Kindle Bookstore or if you don’t have the mental energy to figure this whole Kindle thing out, you can now buy a PDF version of The Ultimate Kumon Review directly from Maths Insider which you can read on your phone, tablet, laptop, desktop without needing any extra software.

That’s one more thing you can cross off your to-do list.

Can You Pass The Maths Test For Teachers?

MATHS INSIDERS bloggs (4)

This is a guest post by Adrian Beckett,  maths tutor extraordinaire

A background to the QTS Skills Test

The The Training and Development Agency for Schools (TDA) Qualified Teacher Status (QTS) Numeracy Skills Test is a scary test that all trainee teachers in the UK have to pass before applying for any teacher training course, even if they want to train to teach 5 year olds.  Budding teachers dread it. Passing the test can mean the difference between pursuing their dream of becoming a teacher and NOT.   Our goal at Adrian Beckett Tutors is to enthuse these intrepid teachers with our passion for Maths.

So what’s this test all about?  And if I’m a parent why should I read on?.

QTS Example Numeracy Question for aspiring UK teachers

 

It’s a test that has 2 sections:  mental arithmetic and interpreting and using statistical information. In the mental maths section, you have 18 seconds to answer a spoken question.  Many adults find this very difficult to do.  You should read on if you’d like to improve your mental maths or if you are a trainee teacher and need to pass this test.

QTS Example Numeracy Question for aspiring UK teachers

 

What does Adrian Beckett and his gang of Maths tutors (www.adrianbeckett.co.uk) want?

 

I WANT YOU TO FEEL CONFIDENT ABOUT MATHS.

In this post, I’m going to give teachers and parents alike, strategies for rocking at Mental Maths.  The strategies I’ll give you are based on the way children learn maths intuitively at primary/elementary school.

How to Learn the Times Tables

Over and over, children are told to learn their times tables by memory.  Look – don’t get me wrong, you need to know your times tables quickly but when you are starting out –  memorizing is not the answer.  Faced with 100 facts to learn, it can be overwhelming.

The 2’s – I bet you know these because you know how to double and half  numbers.

The 10’s – add a zero.  E.g 7 x 10 = 70.  Easy.  Right!

The 5’s.  You know your 10’s. E.g 8 x 10 = 80 so 8 x 5 is half of 80 = 40

The 3’s.  If you are going to memorize any timestables, memorise this one.

The 4’s.  Double 2 is 4 so if you have 4 x 8.  Do 2 x 8 = 16.  Double it.  You have your answer.  You could also use building blocks

The 9’s. e.g 8 x 9.  Swich it – 9 x 8.  So 10 x 8 = 80 and take away 8 = 72.

For the rest of the times tables, use building blocks.  6, 7 and 8 are the hardest timestables and when you are panicking, having some sort of support can be reassuring.  Memorisation is no good for those panicky moments.

Check this slide out to see what I mean. Your building blocks are the 5 and 10 times tables.

Screen Shot 2013-03-07 at 19.51.52

If you want to do 6 x7, do 5 x 7 = 35 and then add one 7 because you’ve done 5 sevens but you need 6 sevens.   35 + 7 = 42.

If you want to do 9 x 7, do 10 x 7 = 70 and then subtract 7 = 63

If you want to do 8 x 7, do 5 x 7 = 35 and add 3 x 7 = 21 and then add the two, 35 + 21 = 56.  Ok, that’s not so easy you might like to memorise this one.

Another trick is to remember the square numbers.

6 x 6 = 36

7 x 7 = 49

8 x 8 = 64

If you want to know 7 x  6 then you have 36 and add 6 = 42.

Some people find songs and rhymes such as I was sick and sick on the floor, 8 x 8 is 64.  You can try this too.

Have You Seen These 10 Fab Science and Math You Tube Channels?

MATHS INSIDERS bloggs (6)

These days my 2 older kids (aged 11 and 13), come home from school, grab some food from the pot (if I’ve been organized!), some fruit from the fridge or put some bread in the toaster. They then sit down at the breakfast bar, open up You Tube on the the kitchen computer and watch a few science videos. If  I’m in the kitchen, I’ll usually get drawn in and start watching some video about whether zero is an even number, or what’s the longest straw that a person can suck a drink from or some other piece of coolness related to science, technology or medicine (STEM)

You Tube scienceWhat’s interesting is that my kids are perfectly happy to watch a science video even if it doesn’t have fancy graphics or special effects, as long as the topic is interesting. Most of these videos are relatively short (3-15 minutes) so they’re perfect for a quick before/after school bite of science. I highly recommend these You Tube Channels to pre-teens and teens, but even my 6 year old has been known to insist that a video is restarted, so that he can find out about an interesting bit of science.

So in no particular order, here’s my Top 10 Science and Math You Tube Channels, along with their tag line, my short description and my current favorite video from each channel. Enjoy!

1. Numberphile

About Numberphile: Videos about numbers – it’s that simple. Videos by Brady Haran

I love the way that Brady Haran and his team of mathematicians bring out the beauty of mathematics. These videos don’t use fancy video techniques but you’ll love the enthusiasm of the presenters as they reveal fascinating examples of how numbers and math contribute to the world. Many of the concepts use higher level math, but even if you don’t understand the math (I don’t always) you can’t fail to be drawn into their mathematical world.

2. VSauce

About Vsauce: Our World is Amazing. Subscribe for Mind-Blowing Facts & The Best of the Internet

Without wanting to have favorites, VSauce is actually one of the channels on this list that I do watch every week. Michael from VSauce has a great way of starting off with a really interesting question such as “Why is Yawning Contagious, giving you the answer, but also bringing in lots of other related ideas that make you think literally, “That was cool!” VSauce videos have plenty of cool graphics to keep even the most distracted viewer entranced.

3. Brusspup

About brusspup: Optical illusions, Science and more!

Featuring some of the coolest optical illusions on the internet, Brusspup short videos tease the viewer by showing you the reality behind the illusions. These videos are a great way of introducing arty students to the way in which science and art are inter-linked.

7. ViHart

About Vi Hart: I’m a professional mathemusician at Khan Academy

Now working with Salman Khan at Khan Academy, Vi Hart is a favorite of math lovers everywhere. Her quick and beautifully drawn doodles highlight some of the cooler math concepts, while Vi’s friendly but speedy voiceover is a perfect way to demonstrate the excitement of the math she’s sharing. Don’t worry, you won’t understand everything she talks about but you’ll definitely be impressed by the math!

8. Smarter Everyday

About Smarter Every Day: I explore the world using science. That’s pretty much all there is to it. Watch 2 videos. If you learn something AWESOME, subscribe.

In the presenter’s own words “The goal is simple. Instead of just setting money aside for my 3 kids’ college fund, I spend it on making videos to educate the masses. Any donations I receive or revenue from the videos then becomes the college fund. This makes me more aggressive at saving for their college, and EVERYBODY GETS TO LEARN!” If your kids like science experiments, they’ll love Smarter Every Day.

9. Veritasium

About Veritasium: The science video blog from atoms to astrophysics!

More cool questions and more science experiments. Veritasium brings you the experiments behind the science and gives the viewer a cool insight into how scientists test out their theories.
