SK Grade 8 Math
I had a peek at
First I would have students play around with coloured tiles which represent negative and positive integers. (review addition/subtraction of integers) Then I would show the video, but stop during viewing so discussion could begin about how they would group/unitize the tiles. After discussion, we’d watch the solution. Over the course of a few lessons, we’d develop the rules to multiply integers.
I also like how the number line is included in this video as another way to visualize the process. Teaching multiplication with number lines was something I always found difficult. The above video makes so much sense!
