This term in Maths we have really been focusing on ordering numbers to ten and understand all of the different ways in which we can represent the number ten. We have recently started to work on addition and have been looking at the part whole model to help us really understand addition number sentences. We have been looking at partitioning numbers in lots of different ways - partitioning just means splitting up the numbers!
In a part whole model we know we have a whole number. This number is then split up into parts (partitioning). So for example if we had the whole number 8 we could split this up into 4+4, or 5+3, or 6+2. We know that when we are adding our whole number will always be a larger number as we are starting with a small number and adding some more. Therefore the whole number will be larger. The part whole model has really helped us to understand the reason why we can't have number sentences such as 8+5=3.
We also know that we can partition a number into more than 2 parts. So we could partition the number 8 by doing 1+1+1+1+1+1+1+1=8 or we could do 2+2+2+2=8 or 3+3+2=8. The part whole model is a really visual way to help us understand this. Have a look at an example of a part whole model! What do you think?
