Divisibility Challenge
You need:
- 2 Players
- A die labelled 1 to 6
- A calculator
How to Play:
Player A rolls the die and records the number.
Player B rolls the die.
Player B adds a digit to Player A circle number so that the new number is divisible by the number rolled.
Player A uses a calculator to check.
Player A rolls the die.
Player A adds a digit to the 2-digit number so that the new number is divisible by the number rolled.
Player B uses a calculator to check.
Players continue to take turns until a number formed is not divisible by the number rolled.
Example:
Player A rolls a 3.
Player B rolls a 2. Player B adds a circle 4 to 3 & to form 34, which is divisible by 2.
Player A rolls a 4. Player A adds a circle 8 to 34 & to form the number 348, which is divisible by 4.
Play continues.
Some Questions to get the collaborating going:
- What age group is this best for or how could it be adapted for a different age?
- Could you help make it even more clear (so a child/student could understand it)?
- How can it be adapted to teach a different math skill?
