How to play
- Look at how each number changes to the next.
- Check that the same rule works all along the row.
- Tap the number that comes next.
Choose Relaxed for ten questions with no clock, or Race to answer as many as you can in sixty seconds. After a wrong answer the game shows the right one and the reason. At the end it lists the questions you missed and keeps your best score for each level on this device.
Levels
- Level 1: Counting on and back
- Level 2: Bigger steps and doubling
- Level 3: Growing steps, squares and more
Start at the level where about eight answers in ten are right, and move up when it feels easy.
What this game practises
Spotting a rule and using it to predict is the heart of mathematics, and the first step towards algebra. Skip counting leads to tables, doubling leads to powers, and steps that grow lead to square and triangular numbers. Just as useful is the habit this game teaches: test your idea on every term before you trust it.
Tips for parents and teachers
- Ask the child to say the rule in words before tapping.
- Write the differences between the numbers underneath. The pattern often shows there.
- Let the child make a pattern for you to solve.
Play it without a screen
One player writes four numbers that follow a secret rule. The others guess the next number and then the rule. Clapping patterns work for very young children.
