Purpose:
You can help your child practice multiplying numbers by 10, 100 and 1000.
What you need:
- Game board (PDF,60KB) . You can print these or make your own.
- Cardboard.
- Dice.
- 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.
- Example 1: If a player rolls a 4 they can cross off the number 20 000 by writing any of the following: 2 x 10 000, 20 x 1 000, 200 x 100, 2 000 x 10, 20 000 x 1.
- Example 2: If a player rolls a 3 they can cross off the number 3 000 by writing any of the following: 1 x 3 000, 10 x 300, 300 x 10 or 1 000 x 3
Game board A
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.

He Whakawhitinga Kōrero:
- Kei a koe i te tuatahi. Pīrorihia te mataono tau. (You go first. Roll the dice.)
- Kua pīrorihia te whā. Koirā te maha o ngā kore i tētahi o ngā tau i tō papa tākaro. Tohua tēnā tau. (A 4 has been rolled. Thats the number of zeros in a number on your game board. Point to that number.)
- He aha tētahi whakareatanga e hua mai ai tēnā tau? (What is a multiplication that will produce that number?)
- Tuhia te whakareatanga ki te pepa. (Write the multiplication on paper.)
- Whakareatia te tekau mano ki te rua, ka rua tekau mano. (Multiply 10 000 by 2 and you get 20 000.)
- Uhia tēnā tau ki te porotiti. (Cover that number with a counter.)
- Kua uhia katoatia ngā tau i tō papa tākaro, ko koe te toa. (You’ve covered all the numbers on your game board, you’re the winner.)
