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.
