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.
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).
