This lesson is optional because it does not address any new mathematical content standards. This lesson does provide students with an opportunity to apply precursor skills of mathematical modeling.
In previous lessons, students analyzed and represented categorical data using picture and bar graphs. They generated statements, expressions, and equations based on the data in graphs and other displays.
In this lesson, students work in pairs to create their own survey question, collect categorical data, organize their data, and represent their findings with a bar graph or picture graph. Students are invited to represent comparisons with a tape diagram and equation that reflect what they learned about their classmates from their data.
This lesson supports the development of mathematical modeling skills by providing students opportunities to make choices about their approach for collecting data, determine appropriate equations to represent the situation, and choose ways to best represent their analysis (MP4).
This lesson is allocated to be more than 60 minutes, but it can be adjusted to meet the needs of the students. The activities can be modified to fit within 1 day or extend to span over 2 days.
- Collect, organize, and represent data from survey questions.
- Create questions related to survey data.
- Interpret results of a survey and represent findings.
- Hagamos nuestras propias encuestas para conocer mejor a nuestros compañeros de clase.
