Distributive Law for Excess and Shortage Problems in PSLE Math
Ho Soo Thong
This article illustrates the use of Arithmetic Distributive Law as essential mathematics for problem solving at primary school level. It begins with a bar modelling approach to relate the mathematical situations in some word problems to the Distributive bLaw. A further step forward is to use the similar approach to complex Excess and Shortage problems.
