Multiplication
We are learning to:
write number sentences to describe an array.

I have 12 counters.
How could I arrange them into equal rows?

What number sentences could you write to go with this array?
2 x 6 = 12
6 + 6 = 12
2 + 2 + 2 + 2 + 2 + 2 = 12

Can you think of any other ways to arrange the counters?

What number sentences could you write to go with this array?
3 x 4 = 12
4 + 4 + 4 = 12
3 + 3 + 3 + 3 = 12

Could you arrange 20 counters?

What number sentences could you write to go with this array?
2 x 10 = 20
10 + 10 = 20
2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 20 OR …

4 x 5 = 20
4 + 4 + 4 + 4 + 4 = 20
5 + 5 + 5 + 5 = 20
