What is the RFPD Topic?
RFPD stands for Ratio, Fractions, Percentage and Decimals. It is an iSchool topic that groups these closely related concepts together, helping students understand how they are connected and apply them more effectively when solving PSLE Math questions.
What is the Strategies Topic?
The Strategies topic helps students develop systematic approaches to solving multi-step PSLE Math problem sums. Instead of focusing on a specific mathematical topic, it teaches students how to recognise question patterns, identify the relationships between quantities, recognise the underlying problem-solving concepts, choose the most appropriate solving technique, and determine the value of one unit before completing the solution.
Examples include:
Students can practise unlimited variations of each strategy using Generate New, helping them recognise when and how to apply each method confidently across different problem sums.
Examples include:
- Units Method
- Fraction to Units
- Units Manipulation
- Other commonly used problem-solving strategies.
Students can practise unlimited variations of each strategy using Generate New, helping them recognise when and how to apply each method confidently across different problem sums.
What is the Mental Sums Topic?
The Mental Sums topic helps students develop the speed, accuracy and number sense needed to solve calculations mentally without relying on written working. It strengthens recall of basic facts and encourages students to recognise number patterns and use efficient mental strategies to solve questions quickly.
Examples include:
Students can practise unlimited variations of Mental Sums questions using Generate New, helping them improve calculation speed, accuracy and confidence for both school exams and the PSLE.
Examples include:
- Addition and subtraction
- Multiplication and division
- Fractions, decimals and percentages
- Number patterns
- Estimation and quick calculations
Students can practise unlimited variations of Mental Sums questions using Generate New, helping them improve calculation speed, accuracy and confidence for both school exams and the PSLE.
Are the questions suitable for different ability levels?
Yes. Most Topics include questions across three difficulty levels, allowing students to learn at a pace that matches their current ability and gradually progress to more challenging questions.
Students should begin at a level suited to their current ability and progress only after they can solve the questions accurately and independently.
Students should begin at a level suited to their current ability and progress only after they can solve the questions accurately and independently.
What do Level 1, Level 2 and Level 3 mean?
Questions are arranged into three difficulty levels to help students progress systematically.
Students should begin at a level that matches their current ability and progress only after they can solve the questions accurately and confidently on their own.
- Level 1 (Basic) – Builds a strong foundation through straightforward question types that reinforce fundamental concepts.
- Level 2 (Intermediate) – Develops deeper understanding by applying concepts to more challenging and multi-step question types.
- Level 3 (Advanced) – Challenges students with complex PSLE-style questions that require deeper reasoning and advanced problem-solving skills.
Students should begin at a level that matches their current ability and progress only after they can solve the questions accurately and confidently on their own.
Are iSchool's questions organised according to the Singapore MOE Primary Mathematics syllabus?
Yes. iSchool's questions are organised according to the Singapore MOE Primary Mathematics curriculum from Primary 1 to Primary 6.
- Questions are organised by Level, Topic and Concept, making it easy for students to follow what they are learning in school.
- Students can practise topics in the same sequence as the school curriculum or focus on specific topics and concepts that require additional practice.
- Students can also practise topics above or below their current school level based on their learning needs and progress.
Does iSchool follow the latest MOE Primary Math syllabus?
Yes. iSchool's questions, worksheets and exams are regularly reviewed and updated to align with the latest MOE Primary Mathematics syllabus. When the syllabus changes, outdated question types are revised or replaced with questions that reflect the current learning objectives.
