3 Act Math Task: Donut Delight

The main math task explored was Donut Delight where we played with multiplication to predict how many donuts there were in the “double hundred dozen” box and then used repeated subtraction to lead to a flexible division algorithm for division when we tried to find how many layers there were. To see all kinds of different representations and access all of the resources, head to this post here:


Japanese Multiplication

In some of the groups, one of the multiplication strategies we explored was Japanese multiplication. You can view the post below:

Here’s a video that gives a detailed explanation of Japanese multiplication.
