We have been solving problems using our knowledge of addition by combing the parts. For example...
Which equation matches the picture?
3 + 3 = 6 8 = 4 + 3
5 = 4 + 1 4 + 3 = 7
Explain your answer.
Explain why the others can't be right.
We have been using our knowledge of the part - part - whole model to solve missing addend equations. 2 + ? = 10
We have been learning addition by aggregation. This means representing a whole group split into parts. These parts are called the addend. We learned that the addends can go in any order and it does not change the sum of the parts together.
3 + 4 = 7 4 + 3 = 7
We have been using the part - part - whole model to represent whole numbers. We did this first with cubes, then used pictures and then used numbers to represent this. We used the part - part - whole model in different orientations.
We have been showing our understanding of the place value of numbers by regrouping. Every time we got ten ones, we had to swap them for one group of ten.
We have been representing numbers in different ways using different maths resources. See the gallery for more photos.
