# Multiplying by 10, 100 and 1000

The Ministry is migrating nzmaths content to Tāhurangi.
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz).
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024.
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

### 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.)
