Bits and Pieces I focuses on developing a deep understanding of rational numbers. In this unit, children will learn the meanings of fractions, decimals, and percents, and will become comfortable moving among these three representations of rational numbers. Children will work on problems that reflect different contexts and that involve writing, comparing, and ordering fractions and decimals. This unit makes use of models, such as fraction strips, number lines, and grids. Skill with estimating and comparing is developed through a set of benchmark fractions and their decimal equivalents.
