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
