In grade 2, students learned how to draw and label single-unit scale bar graphs and picture graphs and used categorical data presented in graphs to solve simple problems. In this lesson, students revisit the structure of picture graphs and bar graphs, the features of graphs that help communicate information clearly, and the information they can learn by analyzing a graph. Students learn that a key is the part of a picture graph that tells what each picture represents. They also learn that the scale is the part of a bar graph that tells what number each bar represents. Students contextualize and make sense of the data based on the title, the given values, and their own experiences (MP2).

Math Community

In the Lesson Synthesis, students discuss what it means to be a part of a mathematical community. Prepare a Math Community poster by drawing a two-column chart as shown. Note that there are sections for students and the teacher to emphasize that both parties are responsible for the way math is done in the classroom. In this lesson, students add their ideas to the “Doing Math”​ column. In upcoming lessons, students will add to and revise these ideas, including drafting classroom goals and expectations for the “Norms” column. Keep the poster displayed in the classroom.

Today’s lesson provided an opportunity to learn from your students. How were you able to incorporate your students’ lived experience into the lesson?
