Maths GamesHow to play
- Read the total at the top.
- Tap an empty box, type a number and press OK.
- Use a full row or column to work out a missing number. Carry on until every line adds up.
A round has no clock. The result screen shows how many you finished and how many slips you made, and keeps your best for each level on this device.
Levels
- Level 1: Four boxes to fill
- Level 2: Five boxes to fill
- Level 3: Different numbers
Start at the level where about eight answers in ten are right, and move up when it feels easy.
What this game practises
A magic square is a logic puzzle built on addition and subtraction. Each missing number is found by taking the two known numbers in a line away from the total, so one puzzle holds a dozen small sums, each needed for the next. Magic squares are very old: the three-by-three square has been known in India and China for many centuries.
Tips for parents and teachers
- Start with a line that has only one gap.
- In the ordinary 1 to 9 square, the middle number is always 5 and the total is 15.
- When finished, check all eight lines aloud.
Play it without a screen
Draw a three-by-three grid and ask the child to place 1 to 9 so that every line makes 15. It takes patience. Give the 5 in the middle as a hint.
