We had to say numbers that we knew that added up to 40. Some people said 90-50 and others said 80-40 and some said 40-0. Some of us also know that 80 divided by 2 makes 40.
We liked that this activity was a little bit tricky and it was fun to be in a group and talk about the numbers we wanted to say.
Next time we want to use bigger numbers like 50 or 100 to make it more challenging.
Do you want to do this activity too as a maths warm up?
Have you done one of these before?
