Division Strategies Revision


  • Halving and Halving Strategy  

E.g. 96 ÷ 24 = 4
48 ÷ 12 = 4
24 ÷ 6   = 4
12 ÷ 3   = 4
  • Using Known Facts Strategy 

This strategy, as the name suggests, involves breaking up the problem into know pieces  to make it easier.

E.g. 136 ÷ 8 = ?
10 x 8 = 80 (136 - 80 = 56)
56 ÷ 8 = 7

There are 10 groups of 8 in the 80, and 7 groups of 8 in 56, so altogether there are 17 groups of 8 in 136, => 136 ÷ 8 = 17.
