The focus of this activity is for students to justify how they know the new number chosen is a factor or multiple of the previous number. Overtime the use (or avoidance) of prime numbers becomes a strategy in this game.
Purpose
- Identify the qualities of a good mathematician
- Demonstrate the qualities of a good mathematician
- Explain and record thinking using a systematic approach
- Identify and explain multiples of different numbers
- Identify and explain factors of different numbers
- Recognise and develop a definition for Prime numbers
- Recognise and develop a definition for composite numbers

- Do all numbers have the same number of factors?
- Do odd numbers have more factors? Or even number?
- What do we call numbers that have only one factor?
- Why are prime numbers special?
- If a number is not a prime, what is it called?
