Solving problems involving addition and subtraction

In this unit pupils will be reviewing and securing previous knowledge of add 3 addends, understanding they can be added in any order, bridging through 10. In the future unit pupils will use known facts to find multiples of ten that compose 100  and use known facts to find complements to 100.

In the prior unit pupils learned to find 10 more or less than a 2-digit number. They added and subtracted 10 to/from a 2-digit number using number facts. In this unit pupils will be reviewing and securing previous knowledge of adding 3 addends, understanding they can be added in any order, bridging through 10.
