1. Multiplication
LI: To be able to write number sentences to describe an array

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

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

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

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

6. Could you arrange 20 counters?

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

8. 5 x 4 = 20
4 x 5 = 20
= 20
= 20

9. Now try doing this on your own.
6 counters
14 counters
15 counters
9 counters
8 counters
18 counters

10. 6 counters
2 x 3 = 6
3 x 2 = 6
3 + 3 = 6
= 6

11. 14 counters
2 x 7 = 14
7 x 2 = 14
7 + 7 = 14
= 14

12. 15 counters
5 x 3 = 15
3 x 5 = 15
= 15
= 15

13. 9 counters
3 x 3 = 9
3 x 3 = 9
= 9
= 9

14. 8 counters
2 x 4 = 8
4 x 2 = 8
4 + 4 = 8
= 8

15. 18 counters
2 x 9 = 18
9 x 2 = 18
9 + 9 = 18
= 18
