Endless humour-wrapped maths cards for Grades 3-6 โ€” the kind kids actually open without being asked. Math Bites is a maths quiz app built around two truths: 1. Kids will do anything if it's funny. 2. ICAS-style maths builds the reasoning that classroom drills miss. So every card wraps a real ICAS-aligned problem in something absurd: a runaway ketchup flood that needs measuring, a courtroom of penguins counting fish, a vending machine that only takes pickles. The maths is real. The scenario is not. WHAT'S INSIDE โ€ข Hundreds of ICAS-aligned cards across Grades 3 to 6 (Papers B, C, D, E) โ€ข Five categories: Number, Geometry, Measures, Chance & Data, Algebra โ€ข Cartoon illustrations on every single card โ€” no exceptions โ€ข Bean's Bag minigames between cards: Balance Beast, Phantom Pan, Chain Reaction, Lock Box, Circuit Spark โ€ข Streaks, achievements, per-category accuracy tracking โ€ข Sit a timed practice test (5, 10, 20, or full 40 questions) FREE TO PLAY โ€ข No account required โ€” try cards immediately โ€ข No ads โ€ข No paywalls in the way of practice PREMIUM (optional) โ€ข Step-by-step worked explanations for every question โ€ข Printable PDF practice packs by grade โ€” screen-free, ready to print โ€ข Same content, no other gating WHY ICAS-STYLE ICAS (International Competitions and Assessments for Schools) is used in 20+ countries and is one of the few primary-school benchmarks that actually tests reasoning, not just computation. Every Math Bites card maps to the official ICAS framework. If your child sits ICAS, NAPLAN, or selective school tests, this is the same shape of problem. Built by parents who got tired of paying $30 for a single-use ICAS practice paper.
