In maths we reviewed number bonds to 10 and began to explore number bonds to 20. We investigated the concept of partitioning and began by partitioning numbers any number between 10 and 20. We continued with addition and subraction sentences to 20 but instead of investigating sums/totals of addition and subraction facts we looked at strategies used to find a missing number within an addition or subtraction sentence. ( 8+ _ = 12) and ( 15 -_ = 13)
