Use only the following dominoes: 0-0 to 0 -10

1-1 to 1- 10

2-2 to 2- 10

3-3 to 3-10

Turn over the dominoes.

Flip a domino and multiply the two numbers.

Example:

This would be 2 × 6

If you answer correctly, keep the domino.

If you answer incorrectly, flip the domino over.

Take out all the jacks, queens and kings. You will only need the aces to tens.

Choose a times table to practice.

Example: to practice the 5 times table

• Choose a single 5 card and place it face up.
• Shuffle the remainder of the cards.
• From the shuffled cards, place one card face up next to the five.
• Multiply. Have your partner check your answer.
• If the answer is correct, leave it on the pile.
• If the answer is incorrect, place the card in front of you.
• Keep turning cards over until there are no cards left.
• Reshuffle any cards in front of you.
• Place a card on the pile and multiply.
• When all the cards are in the pile, you are done.
• Choose a different times table to practice and start again.

Use only the following dominoes: 1-0 to 0 -10

1-2 to 1- 10

2-2 to 2- 10

3-3 to 3-10

4-4 to 4-10

5-5 to 5-10

6-6 to 6-10

7-7 to 7-10

8-8 to 8-10

9-9 to 9-10

10-10

Turn over the dominoes

Flip a domino and multiply the two numbers

Example:

This would be 2 × 6

If you answer correctly, keep the domino.
