Practical Maths

Class 5 worked in pairs to add and subtract 1, 10 and 100. In pairs, one child made a starting number and wrote it on their whiteboard whilst the other child made the same number with place value counters.  Then, the 1st child gave 5 instructions to add or subtract 1, 10 or 100 from the number they had written down. After every instruction, they had to write their answer on their whiteboard. Then, the 2nd child follows the instructions but changers the counters.
