PSLE Problem Sums
Problem sums are difficult because the method is hidden inside the story. Ruiya helps your child slow down, identify the quantities, and begin with a sensible first step.
Ruiya is an AI learning support tool. Parents should supervise use and verify important answers.

What Ruiya can help with
Example starts
These examples show the kind of first step a child can ask for. The exact answer depends on the actual worksheet question and the child's follow-up.
Before-after comparison
Question
There were 3 times as many red beads as blue beads. After 24 red beads were removed, the number of red and blue beads became the same. How many beads were there at first?
Ruiya's start
At first, red beads were 3 units and blue beads were 1 unit. The difference is 2 units. After 24 red beads were removed, the difference became 0, so 2 units = 24.
Working backwards
Question
After spending half his money and then $12 more, Ken had $28 left. How much money did he have at first?
Ruiya's start
Work backwards from the end. Before spending $12 more, Ken had 28 + 12 = 40 dollars. That 40 dollars was half of his money.
Parent questions
Ruiya should earn trust through patient explanations, transparent limits, and parent feedback tools.
Many problem sums hide the method. The child must identify what changes, what stays the same, and which quantity can be used as one unit or one part.
Ruiya can explain model-method style thinking when the question suits it, and can also use other Singapore Primary Math methods when a model is not the clearest path.
