Weather watchers
http://illuminations.nctm.org/LessonDetail.aspx?ID=L287
A lesson plan for grades 3–5 Mathematics
Students collect and analyze data about the weather and learn to make a stem-and-leaf plot. Students use newspapers, the Internet, or other sources to collect weather data. Illuminations provides links to helpful web resources and detailed instructions for completing the activity.
Students will:
- Collect, organize, and describe weather data.
- Construct, read, and interpret different displays of data, such as line graphs, line plots, and stem-and-leaf plots.
- Formulate and solve problems that involve collecting and analyzing data.
NCTM Standards and Expectations:
- Represent data using tables and graphs such as line plots, bar graphs, and line graphs.
- Collect data using observations, surveys, and experiments.
- Describe the shape and important features of a set of data and compare related data sets, with an emphasis on how the data are distributed.
