CCSS Practice Standard 2This collection aims to shed light on Practice Standard 2: Reason abstractly and quantitatively, and offers instructional strategies for helping students make sense of quantities and their relationships in problem situations. These resources provide meaningful ways to support children as they learn to represent problem contexts with numbers and symbols, and then re-interpret the numbers and symbols in terms of the original problem. A companion Classroom Collection includes resources to help teachers develop this practice with their students.
