Number Skills
Times tables, sums & sudoku
Free · In‑App Purchases
Practice arithmetic, square numbers, statistics and probability, fill in the whole times table grid and solve new sudoku puzzles. No ads, no internet needed.
Number Skills is math practice for children aged 5 to 12 — designed like a squared exercise book where you calculate, fill in and solve at your own pace. New problems are made every time, and each round is 10 timed problems.
ARITHMETIC
• Addition and subtraction from the number line up to five digits, with carrying and borrowing
• Multiplication and division from the small tables up to 3 × 2 digits and 3 digits ÷ 2 digits
• Fractions — from recognizing a fraction to simplifying it
• Decimals, including multiplying with decimals
• Mixed, when everything comes together
SQUARE NUMBERS
From 2² with squares to count, up to big square numbers and square roots.
STATISTICS AND PROBABILITY
Mean, median, mode and range — and probability with marbles, dice and spinners.
TIMES TABLE GRID
Fill in the grid cell by cell — from the 3, 4 and 5 tables to the whole grid from 1×1 to 9×9. A correct answer moves on right away, and the hint counts up the table for you.
SUDOKU
Four levels with a new puzzle every time. Every puzzle has exactly one solution. Use notes, the eraser and up to three hints.
YOUR PROGRESS
See how many problems you have solved, how many you get right, and your best times in every category.
