  • Number: Addition and Subtraction

Having previously explored equivalence and compensation in addition, pupils now explore these in the context of subtraction where they will consider constant difference and how increasing or decreasing the whole (minuend) and known part (subtrahend) affects the difference. They will apply known facts and strategies to solve problems in a range of contexts. This will prepare them for solving problems with larger numbers and to apply equivalence in different contexts.

  1. Explain and represent constant difference for subtraction
  2. Explain how constant difference can make written calculations more efficient
  3. Use constant difference to balance equations and find unknowns
  4. Explain how increasing or decreasing the minuend affects the difference
  5. Solve subtraction calculations mentally by using known facts
  6. Explain how adjusting the minuend can make mental calculation easier
  7. Explain how adjusting the subtrahend affects the difference: reduction structure
  8. Explain how adjusting the subtrahend affects the difference: partitioning
  9. Calculate the difference using knowledge of an adjusted subtrahend: difference structure
  10. Use equivalence and compensation strategies to solve subtraction problems in a range of contexts
