Multi-age 3–6, mathematics, Year B – Unit 13

This multi-age unit develops the big idea that multiplicative thinking involves flexible use of multiplication and division concepts, strategies and representations.

In this 2-week unit, students are provided opportunities to:

  • select and apply strategies to solve problems involving multiplication and division with whole numbers
  • investigate and apply the use of multiples to determine unknown values (Stage 2)
  • use number properties to find related multiplication facts (Stage 2)
  • multiply and divide decimals by powers of 10 (Stage 3)
  • investigate the order of operations using real-life contexts (Stage 3).
