Procedure
- Choose a number of the day, say 18.
- Children use that many plugs and find as many ways as possible to arrange them in equal rows, with left overs if necessary. Colour can be used to highlight the arrangement.
- Children record in their journal (Poly Plug Paper may be useful) and check their recording with a calculator.
For example, this one illustrates:
- 18 ÷ 7 = 2 rem 4
- (2 x 7) + 4 = 18
- 7 + 7 + 4 = 18
- 18 - 7 - 7 = 4
