I saw this cool comic strip below, by the funny folks at Saturday Morning Breakfast Cereal (SMBC), a few weeks ago on Facebook , and spent a good few minutes cry-laughing (is that a thing?) Even my daughter in the midst of wrangling with quadratic equations in preparation for a math test, joined in. You see, even for seasoned math teachers, math lovers and professional scientists and mathematicians, arithmetical errors are all too common when problem solving.
As part of my role as Instructor for International Students at Thinkster Math (formerly Tabtor), I was given 5 math worksheets at Grade 5 and 6 level to test and report back on any errors or inconsistencies before the worksheets were released onto the student app. Needless to say I made 1 or 2 (or 5) mistakes across the set of worksheets!
