Unit 1 Overview - Rational Numbers

This unit bundles student expectations that address sets and subsets of rational numbers, ordering rational numbers, and converting between standard decimal notation and scientific notation. During this unit, students continue to examine the sets and subsets of rational numbers and use a visual representation, such as a Venn diagram, to describe the relationships between the sets and subsets. Rational numbers are the focus of this unit as students order a set of rational numbers that arise from mathematical and real-world situations. Students extend previous understandings of the relationships within the base-10 place value system as they convert between standard decimal notation and scientific notation. Both positive and negative numbers are represented with standard decimal notation and scientific notation, including values greater than and less than one.
