1. LO To explore patterns in linked division calculations
Mrs L A Forster

2. Use your calculator to find the answers.
4000 ÷ 32 =
2000 ÷ 16 =
1000 ÷ 8 =

3. What do you notice ? 4000 ÷ 32 = 125 2000 ÷ 16 = 125 1000 ÷ 8 = 125
Why does the answer stay the same?

4. Can we make our own sequence of linked division calculations?
3840 ÷ 12 = 320 so

5. Can we make our own sequence of linked division calculations?
3840 ÷ 12 = 320 so
1920 ÷ 6 = 320

6. Can we make our own sequence of linked division calculations?
3840 ÷ 12 = 320 so
1920 ÷ 6 = 320 So
960 ÷ 3 = 320

7. So can you solve this division without your calculator?
480 ÷ 1.5 =

8. So can you solve this division without your calculator?
480 ÷ 1.5 = 320

9. What would happen if we doubled the numbers?
36 ÷ 6 = 6
72 ÷ 12 = 6
144 ÷ 24 = 6
288 ÷ 48 = 6

10. What else could we do to create a pattern of linked division calculations?
x 10?
÷ 4?
x 3?
÷ 8?
