CapyMaths - Primary Maths UK

Your child's maths practice shouldn't be guesswork. CapyMaths uses AI to find exactly where they need help — aligned to the UK National Curriculum from Year 1 to Year 6, with dedicated SATs Prep and 11+ Maths sections. Created by a dad for his own daughters, now available for every UK family.

42,000+ QUESTIONS — YEAR 1 TO 11+

Every question mapped to UK National Curriculum objectives:

- Year 1-6: 26,300+ questions covering number bonds, place value, addition, subtraction, multiplication, division, fractions, decimals, measurement, geometry and more
- SATs Prep: 8,900+ questions across arithmetic, reasoning, fractions, measurement, geometry and ratio — aligned to KS2 SATs Papers 1, 2 & 3
- 11+ Maths: 6,800+ multiple choice questions in GL Assessment style, covering number, algebra, sequences, ratio, geometry, data and multi-step problem solving

SMART AI PRACTICE

Our AI analyses your child's answers in real time, identifies weak spots, and builds a personalised practice programme. Smart Practice targets areas that need improvement, adapts difficulty as your child progresses, and uses time and skip data to find hidden weaknesses.

THREE WAYS TO PRACTISE

- Self Practice — choose any topic from your child's year group
- Smart Practice — AI picks the questions your child needs most
- Challenge Mode — timed challenges to build speed and confidence

RETRY ZONE — MASTER YOUR MISTAKES

Every wrong answer is automatically captured. Your child retries the exact question, then proves understanding with a similar question from the same topic. Two correct answers and it's graduated. No more repeating what they already know — just focused practice on real weak spots.

CAPYBARA COMPANION

Your child earns River Coins through practice, then uses them to feed, dress and care for their virtual Capybara. Choose from 14 backgrounds, unlock equipment, play 6 mini-games, add friends and send gifts. It turns "I don't want to" into "can I do more?"

PARENT DASHBOARD & AI REPORTS

See exactly which topics your child finds tricky. Weekly AI-generated reports delivered to your inbox with strengths, weaknesses and specific recommendations. The dashboard shows weekly trends, Retry Zone progress, and detailed weakness analysis. Download PDF reports anytime.
