In the Primary School Leaving Examination (PSLE) Math paper, students encounter a variety of problem sums that test their mathematical skills and problem-solving abilities. Understanding the different types of problem sums and the strategies to tackle them is essential for success in the exam. In this article, we’ll explore the 7 types of PSLE Math problem sums and provide insights into how to approach each type effectively.

Types of PSLE Math Problem Sums

  1. Before and After
    • These types involve understanding changes or differences in quantities before and after certain events or operations. Students need to identify the initial and final values and calculate the difference or change.
  2. Value and Units
    • Value and units problem sums require students to work with different units of measurement and convert between them. Students must understand the relationship between different units and apply conversion factors correctly.
  3. Gap and Difference
    • Gap and difference involve finding the difference or gap between two quantities. Students need to identify the known and unknown quantities and use subtraction or comparison to find the solution.
  4. Average
    • Average require students to calculate the mean or average value of a set of numbers. Students must understand the concept of average and how to calculate it using the total sum and the number of values.
  5. Ratio Tree
    • Ratio tree involve working with ratios and proportions to distribute quantities among different groups or entities. Students need to understand how to set up and solve ratio trees to find the solution.
  6. Guess and Check
    • Guess and check require students to use trial and error to find the correct solution. Students make educated guesses and systematically test different possibilities until they find the answer.
  7. Work Backwards
    • Work backwards problem sums involve starting with the final result and working backwards to find the initial conditions or steps. Students need to think logically and systematically to determine the sequence of operations needed to arrive at the solution.
