About the KS2 Maths Year 4 Knowledge Retriever

The KS2 Maths Year 4 Knowledge Retriever gives your 8–9‑year‑old the regular, quick-fire practice they need to lock in essential maths skills and build real confidence throughout the school year. Published by CGP, this workbook is designed to work hand-in-hand with everyday learning, ensuring that fractions, times tables, telling the time, geometry, statistics, mental arithmetic, and problem solving don't just get learned—they stick.

Every page is built around short, fill-in-the-blank exercises that test recall and understanding without overwhelming your child. The quizzes provide a simple way to check progress at a glance, and full answers are included at the back so you can support homework without second-guessing. CGP recommends pairing this retriever with their matching Year 4 Knowledge Organiser (available as a money-saving bundle) to give your child a complete learn-then-practise cycle that mirrors the way the English National Curriculum topics are taught in school.

Inside page showing units and time exercises with fill-in-the-blank activities
Fill-in-the-blank exercises on converting units, comparing measurements, money, and 12- and 24-hour clocks help pupils practise key maths concepts

By embedding retrieval practice into your child's routine, this workbook helps transform wobbly knowledge into confident recall—ready for classroom tests, end-of-year assessments, and the step up to Year 5. Your child will develop the habit of revisiting topics regularly, which research shows is one of the most effective ways to secure long-term understanding and prevent last-minute cramming.

Inside page demonstrating time conversion exercises with worked examples
Worked examples and 'Now Try This' prompts guide pupils step-by-step through time conversions and practical maths problems

This is a single physical workbook that ships to your door, ideal for any Year 4 pupil who needs a clear, structured way to revisit and reinforce the core maths topics they're learning in class. Whether you're supporting homework, boosting confidence before a test, or simply keeping skills sharp during school breaks, the Knowledge Retriever fits seamlessly into busy family life.

  • Covers fractions, times tables, telling the time, geometry, statistics, mental arithmetic, and problem solving in line with the Year 4 curriculum
  • Fill-in-the-blank exercises and quizzes designed for regular, bite-sized retrieval practice
  • Full answers included at the back for quick, confident checking
  • Works perfectly alongside the matching Year 4 Knowledge Organiser (available as a bundle)

Frequently Asked Questions

Is this suitable for my child?

The KS2 Maths Year 4 Knowledge Retriever is absolutely perfect for children in Year 4 studying the national curriculum in England.

It is also very useful for children in the devolved nations of Wales, Scotland and Northern Ireland that study similar curriculums.

Finally, the KS2 Maths Year 4 Knowledge Retriever is also very useful for children studying outside of the UK on comparable international curriculums such as the Cambridge Primary Curriculum or The Pearson Edexcel International Primary Curriculum.
