Anywho, after modeling a few different arrays, it was time to get our hands (or desks) dirty and try them for ourselves. As a class we worked through several problems right on our desk using dry erase markers… Here’s a few snap shots of how the kiddos used an array to find the product for the expression, 3 x 4…
I loved how they showed their thinking!
(You can check those out here!)
Those multi-sided dice made differentiated our partner practice a breeze! My kiddos that were still working on using arrays were given dice with only 7 or 8 sides. The kiddos that were already starting to see arrays with in arrays and had a strong handle on multiplication were given up to 12 sided die.
Here’s a shot of an array one of my mathmaticians made using the 12 sided dice.
Look at that math on the side there!
Here’s a pair of students TRYING to use an array to solve 9 x 9…
Look at that addition over there! Don’t worry! Eventually, they found that they could split their array into 5 x 9 and 4 x 9 to get 81! I can’t wait to continue our array practice tomorrow with stickers! I’d love to hear your favorite way to teach multiplication! Comment below!
