### Purpose:

You can help your child practice adding and subtracting with hundreds, tens, and ones.

### What you need:

- a die
- pen and paper for each player

### What to do:

Before play begins players need to agree on the starting number and the target number and record these on their paper. Choose three-digit numbers between one and a thousand.

Players take turns to throw the die. They then choose to add or subtract the number thrown to the hundreds, tens or ones of the starting number. For example, if a 5 is thrown players could add or subtract 500, 50 or 5 from the starting number.

With each successive turn players add or subtract numbers to the result of their previous turn.

The first player to reach the target number exactly wins.

### What to expect your child to do:

- Understand place value so that hundreds, tens and ones can be added together.
- Consider how much more is required to reach the goal number.
- Develop a strategic approach to the placement of numbers.

### Variations:

Increase the place value to include thousands.

*(Roll the dice. The number that comes up is the number of hundreds, tens or ones that you either add or subtract to your starting number. For example, if a 5 comes up you decide whether to add or subtract either 500, 50 or 5 to or from your starting number.)* - Kei a koe i te tuatahi.
