Graphing conics made easy. Individuals use an interactive to graph conic sections. The app can handle circles, vertical and horizontal parabolas, ellipses, and vertical and horizontal hyperbolas.

A six-page test covers content from several different high school math courses. It incorporates a few short answer, graphing, and word problems. It also allows room for mathematical reasoning and analysis.

Math is all fun and games with this activity! Learners use an activity designed around hula hoops to collect data. They create scatter plots with their data and then analyze the graphs for correlation. 

Explore nonlinear systems through graphs and algebra. High schoolers begin by examining the different types of quadratic functions and their possible intersections. They then use algebraic methods to solve systems containing various...

Piece by piece ... dismantling a function can highlight interesting patterns. The task asks learners to slice functions in sections with the same vertical change. They then recreate the graph with these slices positioned horizontally....

Algebra and geometry are not interchangeable. Demonstrate why not with a series of problems that deal with the equations of circles and equations of lines that meet specific criteria. 

Sixth graders interpret, create, and display data in a circle graph. In this circle graph lesson plan, 6th graders use a compass, protractors, pizza boxes, and more to create a circle graph and analyze the data they put into it.

For this circle graphs worksheet, students answer multiple choice questions about how to make circle graphs. Students answer 10 questions total.

Fifth graders evaluate data from a circle graph that compares time spent on various activities. They use the computer to manipulate their own data as they compare, examine, create and evaluate data using circle graphs.

In this data collection worksheet, young scholars work with a partner to make 3 small bar graphs after finding the proper number of circles on the first page. They look at a page of a variety of shapes and separate the circles into...
