Question

1. what division problem does the model show?

Explanation:

Step1: Count total blocks per group

Each group has a ten - block (10) and 8 single blocks, so \(10 + 8=18\) blocks per group.

Step2: Count number of groups

There are 3 groups. So total blocks \(=18\times3 = 54\).

Step3: Form division problem

The total number of blocks is 54, divided into 3 groups, so the division problem is \(54\div3\). Also, we can check by seeing that each group has 18, so \(54\div3 = 18\).

Answer:

The division problem is \(54\div3 = 18\)
