Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Connect the size of a rolling cup to the size of circle it makes. Pupils view videos of cups of different sizes rolling in a circle. Using the videos and additional data, they attempt to determine a relationship between cup...

In this transformation learning exercise, students identify a series of transformations and sketch them. They use inversion mapping to establish a one-to-one correspondence between nonzero points. This four-page learning exercise...

A middle school test contains two 40-minute sections covering material through algebra. All questions involve applied problem solving or mathematical analysis.

Young scholars participate in a variety of treasure hunts to promote critical thinking skills. In these problem solving lessons, students go on a photo hunt, scavenger hunt, clue hunt, and map hunt, looking for specific treasures.

A thorough math test divides the content into two 40-minutes sections, covering material through algebra and geometry. Problems incorporate analysis and applied problem solving.

In this algebra worksheet, 11th graders calculate a path taken without repeating and crossing the same path more than once. They are given clues to help-them find the right answer. There is a solution key with his word problem.

In this linear transformation activity, students find a series of linear transformations and sketch them. This four-page activity contains approximately six problems.

Students record their daily activities and graph the results using the educational software program called Inspiration. This lesson is intended for the upper-elementary classroom and includes resource links and activity extensions.

Fifth graders recognize shape and number patterns. In groups, 5th graders use strategies to find patterns. They extend the patterns and give explanations as to how they found the pattern. Students use the computer and the hundreds...

Students practice their math skills in determining the water/land proportions of the Earth. Using globes, they locate the seven continents and oceans and determine which covers more space. They use this information to participate in...
