This week, we are starting to look at addition. We're beginning the week by look at the 'part-whole model'. Think about these things:

How can they be represented? With numbers? Cubes? Counters?
Can zero be a part?
Can they be swapped?
Look at the part-whole model below. Can you see the two parts? Where is the whole?
