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

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

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

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

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

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

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

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

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

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