## Understanding Decimals

In everyday life, we often have measures that are less than one. We can use fractions to represent numbers less than one. Another way to represent numbers less than one would be to use decimals. We will learn that decimals allow for calculations that are consistent with whole number calculations.

We can represent decimals using the

area model (base ten blocks/materials and/or decimal grids).
