3–6 multi-age, Year A – Unit 11

This 2-week, Year A unit develops the big idea that our number system extends infinitely to very large and very small numbers.

Students are provided opportunities to:

  • partition, rename, represent and order numbers up to 6 digits (Stage 2) or up to and including billions (Stage 3)
  • interpret, compare, order and represent decimals up to thousandths (Stage 3)
  • use partitioning and place value knowledge when multiplying and dividing
  • see the inverse relationship between multiplication and division, using the associative and distributive properties of multiplication (Stage 2)
  • use informal written strategies like the area model for multiplication and division problems and represent and solve division problems involving whole number remainders (Stage 3).
