Addition and Subtraction Pick n Mix

Level Three
Number and Algebra
Units of Work
In this unit we look at a range of strategies for solving addition and subtraction problems with whole numbers. This supports students anticipating, from the structure of a problem, which strategies might be best suited to solving it.
  • Mentally solve whole number addition and subtraction problems using a range of strategies.
  • Use appropriate techniques to record mathematical thinking.
  • Predict the usefulness of strategies for given problems.
  • Evaluate the effectiveness of selected strategies.
  • Generalise the types of problems that are...

Partitions

Level Two
Number and Algebra
Units of Work
This unit is about partitioning whole numbers. It focuses on partitioning numbers to “make a ten” or a decade when adding whole numbers, for example 8 + 6 can be solved as (8 + 2) + 4. The unit uses measurement as a context.
  • Partition numbers less than 10.
  • Know and use "teen" facts.
  • Solve addition problems by making a ten, or making a decade.
  • Solve addition problems involving measurements.
