Number > Division

Australian Curriculum Version 9 Says:

Represent practical situations involving equal sharing and grouping with physical and virtual materials and use counting or subitising strategies.

What this means

Given division (sharing and grouping) story problems (orally) students use materials to act out the situation.

  • Sharing problems. Share 12 counters equally among 3 people. One for you one for you one for you … until all counters are shared. How many will each person have? (4)
  • Grouping problems. 15 pencils. How many groups of 3 pencils can you make? Students move groups of three until there are none left. How many groups of 3? (5). When students move these groups of 3 they are using a subitising strategy.

Tips

  • The groups need to be clearly seen. Bowls will help.
  • Acting out sharing and grouping with materials lays the foundation for multiplication and division in Year One.
