# Multiplying by 10, 100 and 1000

### Purpose:

The purpose of this activity is to help your child practice multiplying numbers by 10, 100 and 1000.

### Link to the Number Framework:

Number Facts, Stage 6

### What you need:

Game board (PDF,60KB) . You can print these or make your own.
Cardboard. (Old cereal boxes are good).
A die.
Piece of paper for each player.

### What to do:

Glue the cards on to cardboard. Give a game board to each player. Players take turns to roll the dice. The number on the dice is the number of zeros in the number. For example, 4 means 10 000.
The player then writes on their piece of paper how they will use the dice roll to cross a number off their game board. For example, if a player rolls a 4 they can cross 20 000 (or any number in the 10 000s) by writing any of the following: 2 x 10000, 20 x 1000, 200 x 100, 2000 x 10, 20 000 x 1. Other players check the answer, if it is correct the player crosses off the answer. Encourage your child to use a variety of equations, for example x10, x100 and x100 during the game. The winner is the first player to cross off all the numbers on the game board.

### What to expect your child to do:

To correctly multiply by 10, 100, 1000.

### Variation:

Players get another turn if the number on the dice is both the number of zeros in the number and the non-zero digit in the number. For example, if a dice roll of 1 is used to make 10, or a 2 is used to make 200, etc, then the player gets extra turn.
