This week in Red 1 class we are learning how to subtract.
We have been practising using different things to help us. We could use bead strings, objects, number lines, or counters.
Yesterday we were using what we know about subtraction to answer missing number problems. We are getting very good at it!
Some of us have noticed that we can use addition to help us:
4-2=? We know that 2+2=4 so we can use that to answer the question.
