Grade 2 Unit 9

Representing and Reasoning with Data (10 Days)

Unit 9 Overview:

In unit 9, students generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object to create a line plot. Students will also draw picture and bar graphs (with single-unit scale) to represent categorical data. Students will analyze graphs to solve word problems.

  1. Students will analyze and understand a line plot is a representation of data on a number line. (2.MD.D.9)
  2. Students will use picture and bar graphs to analyze data, with up to four categories, in order to draw conclusions and solve problems about the data. (2.MD.D.10)
