Students examine a sample budget and categorize the entries as a group. Then in small groups they convert budget category totals to percents and degrees to make a circle graph related to a sample budget.

Fifth graders explore to find the central angle and percent. In this circle graph lesson, 5th graders use formulas to calculate the central angle and a protractor to create their graph. Students complete a graphing sheet for homework.

Students make a circle graph. In this graphing instructional activity, the teacher conducts a class survey, then demonstrates how to make a pie graph. When students are comfortable with the material, they use a worksheet to create their...

Students make, read and interpret circle graphs.

Students collect, graph and analyze data. In this statistics lesson, students use circle, pie, bar and lines to represent data. They analyze the data and make predictions bases on the scatter plots created.

Tenth graders construct geometric figures using compasses and protractors.

Students practice making and interpreting pie graphs so they are better able to decide if a pie chart is the appropriate form of display. Students examine included overheads of different pie charts, and directions on how to make pie...

Students construct parallel lines using a protractor and a straightedge. In this geometry lesson, students identify the properties of parallel lines. They use Cabri to graph and observe the lines.

Students discuss the sum of central angles and use string to create them on circles. They find the measure and length of both minor and major arcs. Students give examples of concentric, similar, and congruent circles and congruent arcs.

Examine ratios and proportions in several real-world scenarios. Children will calculate unit rates, work with proportions and percentages as they plan a party, purchase produce, and take a tally. This lesson plan recommends five...
