In these lessons, we will learn how to represent decimals, how to use the decimal notation for fractions with denominators 10 or 100 and how to convert between fractions and decimals.

### 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). Representing Fractions and Decimals Using Base-10 Blocks (Tenths and Hundredths)

Using Base 10 Blocks to Represent Decimals

We can represent decimals on the number line.

### Fractions and Decimals

Standard 4.NF.6: Use decimal notation for fractions with denominators 10 or 100.
For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.
