Additive relations B
Partition, rearrange and regroup numbers to at least 1000 to solve additive problems
  • Use quantity values and non-standard partitioning to solve addition and subtraction problems

  • Model addition with and without regrouping and record the method used

  • Model subtraction with and without regrouping and record the method used

  • Use an algorithm with understanding to record addition and subtraction calculations, where efficient, involving 3-digit numbers

  • Recognise how hundreds are exchanged in subtraction algorithms requiring regrouping

  • Recognise when mental strategies would be more efficient than a vertical algorithm for subtraction (Reasons about relations)

  • Solve subtraction questions with missing digits given the difference (Reasons about relations)

Apply addition and subtraction to familiar contexts, including money and budgeting
  • Use estimation to check the validity of solutions to addition and subtraction problems, including those involving money

  • Reflect on a chosen strategy for solving a problem, considering whether it can be improved

  • Interpret problems involving money as requiring either addition or subtraction

Complete number sentences involving additive relations to find unknown quantities
  • Calculate missing numbers by completing number sentences involving addition and subtraction (Algebraic reasoning)

  • Find the missing number in an equivalent number sentence involving operations of addition or subtraction on both sides of the equals sign (Algebraic reasoning)

  • Create word problems that correspond to given addition and subtraction number sentences
