In this activity, students find intercepts of circular function graphs. They also investigate the characteristics of such graphs.

This lesson was designed for our Grandparents and Special Friends day. It can be used for any visitation day, or an open house. The lesson is designed to review percent of a whole and the sector of the circle representing the percentage....

This activity provides students the opportunity to gain experience in creating circle graphs on the calculator and provides an excellent real-world review of computation with percents.

Students use ideas of ratio and proportion to investigate various ways to make a circle graph. Students create graphs to display the probabilities of the different sums that can be generated with two number cubes. [Requires Adobe Reader.]

Students can use the TI-84 Plus family to graph equations of circles.

Students will learn about the equation for a circle by using a Study Cards stack. Later, students will attempt to match the graph of a circle from a digital picture, using the form learned previously, and approximating the center and...

Students will create data displays using a scatter plot and a line graph of the data and a circle graph of survey data.

In this activity students will contribute a set of random points to a graph of a circle of radius 1 inscribed in a square. They will estimate the area of the circle using geometric probability.

In this activity, students interpret data tables and graphs. They find percentages, and create circle graphs to display data.

Rainforests at the Crossroads: Use a Berlese Funnel to extract arthropods from leaf litter; count and sort the species of arthropods; and use a TI-73 Explorer to make a circle graph showing the different groups represented in their...

Students use small bags of M&M's to make predictions, gather data, and display color distribution results in a circle graph. They explore the concept of ratios and sample size.

Students will measure the circumference and diameter of a variety of different circles. They will graph the class' values of (d,c) on the coordinate plane and use linear regression to approximate pi.

This Learn Check file is a review of writing conic sections given the graph of a conic section. Students are asked to use the graphs to write the equations for a ellipse, circle, parabola, and hyperbola.
