Primary Math model drawing heuristics

Model drawing is a key heuristic method taught to Primary 2/3 students. Mastery of this technique helps solve over 70% of word problems, including advanced topics like fractions, percentages, and ratios. It forms a strong foundation for tackling more complex problems in upper primary levels. In this course, students learn advanced model drawing techniques, which involve multiple steps and careful observation, typically introduced at the P4 and P5 levels.
