In maths this morning, we have been learning about the relationship between adding and subtracting using the bar model. We have discussed how:
- numbers can be commuted in addition (500 + 100 = 600 is the same as 100 + 500 = 600)
- the inverse relationship of numbers which indicates the opposite of something (500 + 100 = 600 600 – 100 = 500)
If you find the time, try practising at home.
