Game
Pi digit race
- ages 10–15
- 30 min
Students practise memorising the digits of pi using rhymes and chains.
Steps
- Show the sentence 'How I wish I could calculate pi': the length of each word gives the digits of pi.
- Students make up their own mnemonic sentences for the next digits.
- In a circle, everyone adds the next digit; anyone who makes a mistake sits down.
- Write the class record on the board.
Tip: Encourage students to group the digits in threes or fours; they are easier to remember.
