Fractions, Decimals, and Percents

We are continuing our work with rational numbers. The major focus is on understanding relationships among fractions, decimals, and percents. Students are making comparisons and identifying equivalent fractions, decimals and percents. They are ordering fractions and decimals, and developing strategies for adding fractions and decimals to the thousandths.

For example, students should be able to accurately and efficiently:

• Compare 5/8 and 3/5 by using percents, representations, or reasoning about their relationship to the landmark fraction ½.

• Compare 0.25 and 0.3 using a 10 x 10 grid and a number line.
