## Eat Your Veggies

In this unit, students collect and display data in a variety of ways, beginning with tallies and pictographs. Later lessons focus on representing data using bar graphs, line plots, circle graphs, box-and-whisker plots, and glyphs.

The students also compare graphs from two sets of data and find the range, median, mean, and mode of each set. They discuss measures of central tendency and range and pose and answer questions about the graphs.

Making and analyzing glyphs offers students an exciting way to display data.

### Tally Time

3-5

Students tally data about food preferences and learn the convention of displaying a set of five tallies. Students also answer pose and answer questions about the data. ### Can You Picture It?

3-5

This lesson builds on the experiences of the previous lesson. Students
collect data about favorite vegetables and record the data in a
pictograph and interpret this representation. They also create and use
legends for the pictograph.### Healthy Eating

3-5

Students collect data about classmates' healthy food knowledge. They create bar graphs, pose and answer questions about the data by looking at the graphs, and find the range and mode. ### What Is Your Favorite?

3-5

Students make human bar graphs and circle graphs, then draw them on paper and use a Web site to generate them. Posing and answering questions using the graphs will give the students an opportunity to apply their problem-solving and communication skills. They will also find the mode for a set of data.### Let's Compare

3-5

Students collect numerical data, generate graphs, and compare two data sets. They also find the mean, mode, median, and range of the data sets. Students communicate with each other and the teacher and practice their problem-solving skills.### Alphabet Soup

3-5

In this lesson, students construct box-and-whisker plots. Students use the box-and-whisker plots to identify the mean, mode, median, and range of the data set. Representation is the major focus of this lesson.### Glyphs for All Reasons

3-5

Students learn a powerful way to display data, the glyph. Representation, communication, and problem solving are important parts of this lesson.
