Progressions for the Common Core State Standards for MathematicsProgressions for the CCSSM: Categorical Data in Grades K-3 and Measurement Data in Grades 2-5

Description: One of a series of documents describing the progression of a topic across several grade levels, informed both by research on children's development and by the structure of mathematics. Students in Grade 2 draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. They solve simple put-together, take-apart, and compare problems using information presented in a bar graph.
