To make larger numbers we use a number system that has place values. The number 64 has 4 in the ones place and 6 in the tens place.

If your child needs help with place value then consider buying linking cubes or something similar to help model numbers.

Here's another chart. This time the shaded column shows numbers with 7 ones and the shaded row shows numbers with 3 tens.

Here are some more numbers shown with digits and with blocks.

Showing numbers on a number line helps develop an understanding of place value. It will help your children appreciate where numbers are positioned relative to other numbers. You will find lots of number lines here.

Use these two place value charts to help your child practice with place values.

- Place Value Chart #1 - Highlight the blocks to match the number shown on the right-hand side.
- Place Value Chart #2 - Write the value of the tens and the ones to make the number shown on the right.

**Hint**: Uncheck the "Show Numbers" box to
print charts onto which you can write any number you like.
