# Counting in Decimals

Pen and paper

### What to do:

Write a decimal number with 2 decimal places. For example 23.21

Name the decimal one tenth more than that number. Write the next five decimal numbers in order.

For example: 23.21    23.31    23.41    23.51    23.61    23.71

Ask your child to write a decimal number with 2 decimal places. For example 35.67

Take turns to name the decimal one hundredth more than that number. For example: 35.68

Have 3 or 4 turns each.

Ask your child to write another decimal number with 2 decimal places. For example: 45.32

Take turns to name the decimal one hundredth less than that number. For example 45.31

Have 3 or 4 turns each.

### What to expect your child to do:

To be able to count forwards and backwards in decimal number sequences.

### Variations:

Extend the activity by asking your child to write a decimal with 3 decimal places and count forwards and backwards in hundredths or thousandths.
