Year 2 have learned to use bar model pictures to represent a sum. We know the 2 smaller bars must be equal to the total of the large bar.
We learned to make a fact family of 2 add sums and 2 inverse take-aways to match a bar model picture. We moved our bars around to check we had all the correct combinations in our family.
We tried to work in an order to find different ways of making the same total i.e 10 + 4 = 14, 11 + 3 = 14, 12 + 2 = 14
