I've been using Exam Ninja books for around five years to help my nine-year-old daughter with her schooling. We buy a set for each year and my daughter works her way through them, a little each day, with my assistance. These are an excellent resource for boosting a child's learning journey and supporting the school curriculum.

About the KS2 Science Year 3 Knowledge Retriever

The KS2 Science Year 3 Knowledge Retriever is designed for seven- and eight-year-olds who need quick, effective practice to lock in what they've learned across biology, chemistry and physics. This CGP revision book uses a fill-the-gaps approach that helps your child recall key facts without flipping through notes, so you can see at a glance which topics stick and which need a second look. Every blank comes with a helpful first-letter prompt to jog their memory, making retrieval feel manageable rather than overwhelming. It's an ideal way to build long-term memory and reinforce the English National Curriculum for Year 3 Science in short, focused bursts.

Fill-the-gap retrieval page covering nutrition topics including animals and food, human diet, and nutrients
Fill-the-gap retrieval activities with letter prompts help children recall key science facts independently

Each spread mirrors CGP's matching Knowledge Organiser, with information removed so pupils actively retrieve rather than passively read. Short quizzes at the end of each section test understanding and confirm that facts are sticking, while full answers in the back of the book let your child self-check or you can quickly mark their work together. The first-letter hints strike a balance between challenge and support, keeping frustration low and confidence high. CGP recommends pairing this retriever with the Year 3 Knowledge Organiser for maximum impact, and both are available together in a money-saving bundle.

Contents page showing topics including Plants, Animals Including Humans, Rocks, Light, Forces and Magnets, and Working Scientifically
Comprehensive contents covering all Year 3 Science topics with topic quizzes and full answers at the back

By the time your child works through plants, animals including humans, rocks, light, forces and magnets, they'll have rehearsed every core fact multiple times in a low-pressure format. The quizzes offer instant feedback, so gaps surface early and you can target extra practice where it matters most. Because the book includes complete answers, there's no guesswork for busy parents—you'll know whether your child has grasped nutrition, skeletons, fossils and more, all aligned to the national curriculum. This physical book ships quickly, so you can start retrieval practice as soon as it arrives.

This Knowledge Retriever suits any Year 3 pupil who's already met the material and needs structured recall to move facts from short-term to long-term memory. The fill-in format works well for regular ten-minute sessions at home, and the letter prompts ensure children stay engaged without becoming stuck. If you want a straightforward, proven way to check what your child remembers and build exam-ready confidence from an early age, this CGP book delivers exactly that.

  • Fill-the-gaps retrieval practice for biology, chemistry and physics across the Year 3 Science curriculum
  • First-letter hints and topic quizzes keep challenge high and frustration low
  • Full answers included at the back for quick parent marking and confident self-checking
  • Pairs with CGP's Year 3 Knowledge Organiser for a complete revision system
  • Physical book ships fast, ready for short daily sessions that build long-term memory
