The Mystery of Multiplication

Multiplication has come a long way since we were in elementary school. We were handed a list of facts and told to memorize. I don't think we even questioned why 4 x 9 equaled 36. We just accepted it.

Things are so different today. Kids not only have to know that 4 x 9 equals 36, they also have to know why. In other words, how do you know? Prove it to me. Which is perfect for my math motto: PROVE IT! DON'T JUST CHOOSE IT!

Our standards no longer just require students to answer the basic fact. The new standards require students to show what 4 x 9 looks like using groups of objects, arrays, and repeated addition. I have created the following products to help my students master these concepts:

I use this Meaning of Multiplication PowerPoint presentation over a week long period. I take each meaning one day at a time. I embed videos and online games into it, so that we can just click and go.

I also use The Mystery of Multiplication lesson and activity packet to provide lessons, printables, games, activities, graphic organizers, and more.
