# Recognising and comparing decimal numbers

In this lesson, students learn about place value and how it extends beyond whole numbers. They use decimal notation to name and represent decimals and use materials to model decimals. These models help students to order and compare decimals that include tenths, hundredths and thousandths.

After completing the lesson, a relevant follow-up activity is Decimats (understanding fractions).
