Learning to read big numbers.

This video will help remind you how to read large numbers.  In Canada, we don't use commas.  We use spaces between each "house," or period.

At home, create a set of digit cards:
1. Cut out 10 pieces of paper or card.
2. Put one digit on each card (0-9).
3. Build a number with more than four digits.
4. Practice reading it.

Use you digit cards to play a game with a partner.
1. Mix up your cards and share them equally between you and your friend.
2. The winner is the person who can create the largest number with their cards.
3. Record who won.  Mix up the cards again and repeat the game several times.
