Multiplication facts are essential for every student.
As students move forward in mathematics into high school and college math, they will rely heavily on their multiplication and division facts. Students start to learn these facts around the age of 7 and it can be a challenge for some. Many teachers simply suggest that students “memorize” all the facts. This is challenging and many children are unable to do this.
The multiplication facts strategy
Eventually we hope that students will just “know” their facts, but when first learning multiplication facts, it is best to teach students strategies for finding the facts, so that they always have a way to find the fact if they forget it.
It also makes them quicker to learn.
Teaching facts should be taught in a particular order, so that the student doesn’t get frustrated, and so that they can rely on their “partner fact” (3X4=4X3) for some of the harder facts.
Before multiplication facts
Before starting, let me stress a prerequisite that must be accomplished before starting multiplication. Students must be adept at addition without counting on their fingers prior to starting multiplication. Specifically, they need to know their doubles.
If you say, 8 + 8, they should immediately know the answer is 16. 9 + 9 = 18. If these doubles are not automatic, start drilling these and then come back to multiplication.
You will also want your child to be able to double twice for the X4 facts, so they should be able to do problems like 14 + 14 and 16 + 16 in their head. The 16 +16 is a harder one since it requires you to carry, I accomplished this one with a song that goes like this: “2 and 2 is 4, 4 and 4 is 8, 8 and 8 is 16; 16 and 16 is 32.”
Use a sing-song voice and the kids learn these doubles quickly including the hard one 16 + 16 = 32!
Some multiplication facts to get you started
Here are some methods for each fact:
X0 Fact: Anything X0 is 0. This is a very easy fact since students just need to learn that anything times 0 is 0. Remind them that 0 sets of something is 0.
X1 Fact: Anything X1 is itself. Again, another very easy fact. For example, 1 X 7, this means 1 set of 7, which is just 7 items.
X2 Fact: Circle the number that is not 2, double that number. Since the student is good at doubling, this is an easy fact.
X4 Fact: Circle the number that is not 4, double the number and double again. The student should have doubling down well before starting, so X4 facts will come very easily to them. The only one that might be difficult is X9 – tell them that they can wait and use the “9’s trick” on that one instead of the 4’s trick if they don’t know 18 + 18 since we didn’t really drill that double.
If you look at the above chart, the only one’s that requires total memorization with no help at all are 6 X 7 and 7 X 7.
Once students get a handle on multiplication facts they can start looking at the concepts of divisibility and division.
