Same goal, different support

With support

Draw six rows of seven. Split the array into five rows and one more row; combine 35 and 7.

Independent practice

Solve the sample, show your method, and check your answer using a second representation or operation.

Extend the reasoning

Create a new example for the same skill. Write a plausible incorrect answer and explain how a model or calculation disproves it.

A misconception to discuss

Adding the two factors counts neither the groups nor the objects in each group. Label both dimensions of an array.
