Use counters to find how many are in each group.

54 counters

9 equal groups

🟧 in each group

So, 54 ÷ 9 = 🟧

Use counters to find how many are in each group.

36 counters

9 equal groups

🟧 in each group

So, 36 ÷ 9 = 🟧

Use counters to find how many are in each group.

56 counters

8 equal groups

🟧 in each group

So, 56 ÷ 8 = 🟧

Use counters to find how many are in each group.

45 counters
