Adding on a number line
We can use a number line to add or subtract numbers from 1-10.
Let鈥檚 try 7 + 2
Start on 7 and jump 2 places further on to finish on 9.
7 + 2 = 9
Subtracting using a number line
To subtract, we jump back to a smaller number.
Let鈥檚 try 6 - 4
Start on 6 and jump 4 places back to finish on 2.
6 - 4 = 2
Example 1
Here is a number line from 0 - 10
Use it to help you work out 4 + 3
Where do you start? How many do you jump? Where do you finish?
4 + 3 means start on 4 and jump on 3 places to finish on 7.
4 + 3 = 7
Work out 8 - 3
Start on 8 and jump 3 places back to finish on 5.
8 - 3 = 5
