The lesson introduces students to dot plots. A dot plot is a graphical representation of data using dots. During the lesson, students are given the opportunity to both interpret dot plots, and create their own. The lesson may be used in conjunction with lessons related to data collection or graphing.
- Begin by explaining to students that summarizing data into a graph or chart helps people to better understand the information.
- While reading the content pages, reinforce vocabulary and give students additional examples of dot plot graphs in order to help them practice. Use the additional resources to enhance understanding.
- Introduce the notes on dot plots. Have students practice drawing dot plots using different amounts for the key. Use the additional resources to enhance understanding.
- Have students practice collecting data and drawing dot plots.
- Follow Activity page with students. Have students work as a class to collect the data for the four questions, this could be individually answering and recording the data or having large sheets around the room for them to post their answers. Once the data has been collected, have students work in small groups to make a dot plot on a large piece of butcher paper or poster board which will eventually be hung in the hallway for other students to see. Have students decorate and be creative!
- Distribute Practice page. Check and review the students’ responses as a class.
- Distribute the Homework page. Have students share their findings at the beginning of the next class.
- In closing, ask students to think about what types of questions would and would not work for displaying data on a dot plot.
- Allow for responses and discussion.
