Description: In Lesson 1, they organize the data and then represent it in a variety of ways, e.g., tally marks, graphs with one-to-one correspondence, or tables. By the end of the lesson, students show data as picture graphs where each picture has a value greater than 1. Students rotate tape diagrams vertically in Lesson 2. These rotated tape diagrams with units of values other than 1 help transition students toward creating scaled bar graphs in Lesson 3. In Lesson 3, students construct the scale on the vertical axis of a bar graph. Lesson 4 provides an opportunity for students to analyze graphs and to solve more sophisticated one- and two-step problems, including comparison problems.*Teacher Advisor is 100% free.
