Students' strategies can be used to provide some of the evidence of their learning.
This task can help with learning ideas for multiplication and division:
  • Fully multiplicative partitioning (Number Framework Stage 7). Fully multiplicative basic facts partitioning attracted students of equal ability to place value partitioning.
  • Using fully multiplicative doubling and halving, or a mix of multiplicative and additive strategies (Number Framework Stage 6).
  • Using doubling strategies involving some addition (Number Framework Stage 6).
  • Using only repeated addition (Number Framework Stage 5). Skip counters were of similar mean ability as repeated adders for this resource.
  • Using only array diagrams (Number Framework Stage 3).
  • Using grouping diagrams.
