This document discusses teaching mathematics using the model method. It begins by explaining the origins of the model method in Singapore, where it was developed in the 1980s to help students with word problems. The model method uses bars or boxes to represent quantities in word problems visually. It then provides examples of how the model method can be used to solve problems involving part-whole, comparison, and change concepts. Several lessons are outlined that teach students how to apply the model method by drawing diagrams and solving sample problems step-by-step.
