If Alex uses his money to buy 8 similar notebooks, he will still have $6 more than Bella. If Bella uses some of her money to buy the same 8 notebooks, she will have $70 less than Alex. How much is the cost of 1 notebook?
This question can be solved easily using model.
16 notebooks --> $64
1 notebook --> $4
Problem sums, even complex sums, can be solved easily using model drawings. This is so as model drawing simplifies the problem and the pictorial representation helps pupils interpret the sum in a more comprehensible manner.
However, the use of model drawing is just one of the many other heuristic strategies used in problem solving. We will be sharing more effective methods, taught in Singapore Schools and we improvise them, to help you better guide your child in their Math homework.
