Rounding big numbers
Purpose:
The purpose of this activity is to help your child learn to round numbers to the nearest 10, 100 or 1000.
Link to the Number Framework:
Number Sequence, Stage 6
What you need:
- Playing cards. (Ace = 1, Jack = 0)
What to do:
Ask your child to take 5 cards and arrange them to make a number.
Ask your child:
- How do you say that number?
- Can you round it to the nearest 10?
- Can you round it to the nearest 100?
- Can you round it to the nearest 1000?
Ask your child to rearrange their cards to make a number close to a thousand number you choose.
For example if the cards are 4, 8, 2, 7, 6 you could ask your child to make a number close to 46000 and expect 46 267.
What to expect your child to do:
- To read the number correctly and to round it to the nearest 10, 100 and 1000.
Variations:
- You could start with 4 cards instead of 5 cards.
- Two players could make numbers and to see who can make the biggest number.
