Description
When PRF questions all seem to need a different method
Your child may manage a basic question but struggle when the wording or number of steps changes. Choosing practice at a suitable difficulty can help you understand where the challenge begins.
Move through PRF practice with a clearer plan
- Three levels of difficulty: help you select an appropriate starting point.
- Star categories for P5, P6 and shared questions: guide your choice of practice.
- Percentage, ratio, fractions and bonus decimals: bring these related revision areas together across two volumes.
Use it together, one step at a time
Begin at a level your child can explain. Discuss what changes in the next level, let them attempt it and use the book as your shared reference. Return to an earlier level if the underlying concept needs more attention.

Here are our new volumes for – “101 Must-Know Direct Questions for Parents – PRF (Volume 3 & Volume 4)” bundle.
That can help your child to spot topical short questions and problem sums on 3 of the most challenging topics – Percentages, Ratio and Fractions.
Why do we create this?
These books provide focused P5/6 practice in percentage, ratio and fractions.
Our maths team reviewed school papers to select the question types in these books.
We discovered THIS!
We discovered a pattern.
We identified three topics that P5 & P6 children find challenging: Percentage, Ratio, Fraction.
Here’s how your child can use these 2 PRF books to study math in a smarter way…
3 Specific Levels of Difficulty
In every section (e.g. Percentage), the questions are grouped into three levels of difficulty.
- Level 1 introduces the basic concepts and present simple sums that uses the 4 operations.
- Questions in Level 2 may require a few steps to solve (often with a less direct approach) or may require knowledge of more than the basic concept.
- Questions in Level 3 are sometimes almost as complicated as problem sums questions, whether it is the phrasing of the question or the thinking process required to arrive at the correct solution.
3 Stars Categories
One star at the end of the question (*) means the question is commonly found in Primary 5.
Two stars (**), means the question is more likely to be tested only at Primary 6.
If you see three stars (***) at the end of the question, the question is tested in both Primary 5 and 6 levels.
Our way of grouping up the questions in this strategic way is to help your child for both P5 and P6.
To help your child score higher, we have also included BONUS questions on Decimals which are getting tougher too.
