### Purpose:

You can help your child know how many tens and hundreds there are in whole numbers.

### What you need:

Sales brochures from the newspaper, for example furniture stores, car sales, electrical appliance brochures. Choose catalogues which have easily read prices.

### What to do:

Select an item, for example a camera that costs $399.99. Ask your child about the money they could use to buy the item.* How many ten dollars notes would you need to buy this camera? Why? *

You would need forty ten dollar notes because that would be $400.* How many $100 notes would you need to buy this camera? Why? *

You would need four one hundred dollar notes because that would be $400.

Repeat using different items and different prices.

When children are confident with these questions, ask them about three and four digit numbers.* How many tens are there in all of 383? *38 tens and three left over* How many tens are there in all of 7 481? *748 tens and one left over* How many hundreds are there in all of 785? *7 hundreds and 85 left over* How many hundreds are there in all of 1 438? *14 hundreds and 38 left over

### What to expect your child to do:

Be able to tell you the numbers of hundreds, tens and ones in three and four digit numbers.

For example: In 563 there are 563 ones in total, 56 tens in total and 5 hundreds in total.

In 7 814 there are 7 814 ones in total, 781 tens in total, 78 hundreds in total, and 7 thousands in total.
