Grade 4

What is a decimal?

decimal

A number that uses a point to show parts smaller than one whole.

For example

The decimal 0.5 and the fraction one half name the same amount.

In Grade 4

Children link decimals to money first, where two places after the point are already familiar.

Watch out for

Children often think 0.5 is smaller than 0.25 because 25 looks bigger than 5. Compare the tenths place first.

Say it at home

Read two prices aloud and ask your child which one is larger, and why.
