• ### Bar Model Method for a Job Problem – A Bi-model Approach

##### Ho Soo Thong

In this article, we will illustrate a bi-model approach to a complex job problem at Primary Olympiad level.

• ### A Direct Bar Model Approach to Number Problems

##### Ho Soo Thong

In the following, we will apply a mathematical implication of Distributive Law and the use of simple arithmetic operations to illustrate a direct approach to two number problems at Primary Olympiad level.

• ### Bar Model Method with Distributive Law For Chicken-Rabbit Approach

##### Ho Soo Thong

This article illustrates a bar modelling of a commonly used problem solving approach to a classical chickens-rabbits problem and advocate the use of this approach to its variants for related word problems.

• ### Bar Model Approach for Averages of Numbers in Statistics

##### Ho Soo Thong

This article illustrates the use of mathematical implications of the Arithmetic Distributive Law for solving problems involving averages at Primary School Level.

• ### Distributive Law for Indeterminate Problems

##### Ho Soo Thong

This article extends the use of Arithmetic Distributive Law in the Bar Model Method to indeterminate distributive problems.

• ### A Direct Counting Approach For Fractions in PSLE Math

##### Ho Soo Thong

This article shows how fractions evolved from the part-whole concept and how a bar modelling approach with Euclidean Algorithm can be used to obtain fractions in a counting approach. Some examples similar to recent PSLE questions will be used to illustrate this approach

• ### 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.

• ### A Direct Bar Model Approach to Concentration Problems

##### Ho Soo Thong

This article illustrates the ratio approach in the Bar Model Method with pictorial view of complex situations in two challenging problems at Primary Olympiad Level.
