Figuring out the right meaning
Divide the class into teams of four and arm them with maths dictionaries. Each team selects a word, writing one correct definition and three false versions.
The aim of the game is to make all versions sound as credible as possible.
A group at a time can then present their definitions to the class, who listen and consult each other before deciding who might be right. They write their answers on a record sheet. After every team has had a go, the record sheets are collected and each team supplies their answer.
DING! And the word is numerator.
1. A numerator is a number which is not a prime number.
2. A numerator is the top digit in a fraction.
3. A numerator is the number occurring most often in a set of data.
4. A numerator is an early sort of counting frame like an abacus
