This week is all about partitioning numbers and finding pairs of numbers that total a number. The children will begin to learn their bonds to 5, 6, 7, 8 and 10. They will also start matching sets of objects to addition sentences and begin to see that addition is commutative, i.e. 5 + 3 is the same as 3 + 5. Children are also introduced to the subtraction sign, using knowledge of bonds.
