Nurturing resilient and confident problem solvers.


Providing an engaging learning environment to develop creative and critical Mathematical thinkers. 

Key Mathematics Programmes

4Cs @YPS is the signature programme for Mathematics in Yishun Primary School. It involves the solving of Mathematical problems using the 4- step approach (adapted from George Polya’s Approach to Problem Solving)

Step 1: Comprehend the problem
  • What are the key words?
  • What is the question about?
  • How would you describe the problem in your own words?

Step 2: Choose the right strategy
  • What are the data given?
  • What are the missing data?
  • How to use the given data to find the missing data?
  • Which strategy to use? Why?

Step 3: Carry it Out
  • Use computation skills (4 operations)
  • Use mathematical tools
  • Use thinking skills
  • Apply mathematical formulae

Step 4: Check the Solution
  • Read the question again carefully
  • Check that the answer is logical and accurate by estimating, substituting or working backwards 

In short, the 4-steps for problem-solving (4Cs)  is
  • Comprehend
  • Choose the right strategy
  • Carry it Out
  • Check the solution


Pupils also use CUBA to help them in the solving of word problems:

Circle the values

Underline the key words

Bracket the question

Arrow to show relationship 

Math Carnival

Primary 1 and Primary 2 pupils have an exciting and authentic learning experience through the Mathematics Carnival. They are engaged in the learning of Mathematics through a myriad of hands-on activities and real-life problem-solving scenarios.

Complementing the content of Mathematics taught in the classroom, the activities have enabled pupils to develop an appreciation for Mathematics beyond the classroom and textbooks and have joy for learning of Mathematics. They apply various thinking skills and heuristics to solve non-routine Mathematics problems. They also use concrete objects and pictorial representations to illustrate Mathematical concepts.

Math & Science Trail

In the effort of making the learning of Mathematics more engaging and exciting, an ICT-infused Math & Science Trail is conducted for all Primary 3 pupils. During this interdisciplinary trail, pupils are given the opportunity to apply Mathematics concepts to solve problems outside the classroom. Hence, this learning experience gives them an opportunity to relate knowledge to reality. The trail also helps to build the pupils' social skills and promote team-building.
