This instructional activity will allow the student to work through three stations. The stations will focus on creating and analyzing circle graphs. The students will be using technology to create their graphs along with a hands-on...

Use Glencoe's randomly generated self-checking quiz to test your knowledge of circle graphs. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the "Check It" button and...

On this interactive website students practice various math skills using a real-life scenario involving plants. Those skills include interpreting data in a circle graph, interpreting data in a divided bar graph, and interpreting a bar...

Two hands-on lab activities for instructors to use when teaching about the coordinate graphs of the sine, cosine, and tangent functions derived from a unit circle. The graphs of the reciprocals of the three functions are investigated....

Use this tool to graph data sets in a circle graph. You can input your own data or alter a pre-made data set.

A lesson plan where students will interpret the trigonometric functions in terms of the unit circle, graph a sinusoidal function, and use a sinusoidal function to make interpretations in a modeling context.

College professor Dan Bach reviews basic trig concepts, including trig functions, right triangles, circles, radians, and polar coordinates. Site includes animated graphs and detailed examples.

This introductory tutorial about statistical graphing with four examples of how pie charts (circle graphs) are constructed and read.

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.

Data comes to the rescue! Children will collect, analyze, and represent data as they try to dodge a series of catastrophes faced by characters from their favorite PBS Kids shows.
