I love this math activity. It’s genius on so many levels! This would help students with addition and subtraction, but also to teach “the 9’s trick” with multiplication! It would be a great introductory/review activity at the beginning of the year, especially to have each student trace their own hands and make one of these themselves.  (source)

I know many parents (and some teachers) don’t like it when kids use their fingers to count or do math. Many see it as a sign of weakness of lack of understanding. However, each time you allow a child to use their fingers (or a hundreds chart or multiplication chart, for that matter) to get the right answer, you’re providing them an opportunity to discover and work for the CORRECT answer. Eventually kids will learn their facts from repetition or they’ll get tired of being the only one without them memorized and they’ll fix the problem. After all, speed isn’t what’s important in math. YES, it definitely helps and it has clear advantages, but it’s not the end-all, be-all. There, I’m done with my soap box; I’ll put it away now. 🙂
