Times tables, on autopilot
Pick the exact facts your child keeps tripping over, like 7 × 6 to 7 × 9, from any table up to 20 × 20. Short drills repeat them until the answer comes before the counting starts.
Math games that feel like play
Number Hunt, Magic Square and Sudoku turn practice into puzzles your child wants to solve. They combine numbers to hit a target and train the same skills without noticing. All the games are free.
Practice at their level
Start on Easy and move up to Extreme when they’re ready, or set the exact number ranges yourself. After a few days of practice, AI Picks spots the facts that slow your child down and suggests a trick to fix them.
Progress you can see
Every test score is charted over time, so you can watch the improvement week by week. Numbio also shows how your child ranks against other players, and against players their own age once enough of them have taken that test.
