Subtraction
Use a number line to subtract a
single digit.
Look at this calculation.
132 – 4 =
The 4 has been partitioned into 2 and
2. This is so when we subtract 2 from 132 we jump back to a multiple of 10
(130). Then we can subtract 2 from 130
which makes 128.
Now try these - show your working out
on a number line
