I’m so impressed with your thorough understanding of multiplication. If only memorizing correct answers, children are likely to have trouble with all future math.

I’m retired now but taught for many years. Please see my four models of multiplication that I taught to my advanced first and second graders. The models promote a comprehension of various ways of understanding of multiplication. They loved the exercises and did very well. These models could be used for any age involved in learning multiplication.

I also have models of addition and subtraction, if you’d like them.

This is a fun read! THanks for not forgetting that middle schoolers and most humans really aren’t prepared to discuss the abstract nature of multiplication (and when we try to take them there, they quickly go to “okay, what does the math teacher want me to say?”) – or, as you’ve noticed, “These kids have given up expecting math to make sense, and they have settled for trying to remember the rules long enough to pass the test.”

Nice series, Bert. It’s been a while since I’ve added a blog to my bookmarks, but I’ll certainly have to visit your site again.

Thanks.
