### 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.
