Just about every public building that your students are familiar with has an access ramp which complies with ADA requirements. As it turns out, designing such a ramp is an excellent activity to incorporate slope, the Pythagorean Theorem,...

High schoolers pretend they are hiking up a mountain. They practice making calculations on angles and elevation. They use topographic maps to estimate distances and trigonometric ratio methods.

Students investigate the surface area and volume of the Luxor Hotel in Las Vegas. They calculate the slant height, lateral edge, and diagonal length of the base. Using this information, students explore other areas of the hotel, such as...

Students evaluate the six trigonometric values of a trig function. In this trigonometry activity, students use the Unit Circle to find the values of right triangles and their angles. They identify an angle of elevation and...

Students differentiate between the slope and the tangent of the horizontal. For this precalculus lesson, students examine slopes created by tangent lines. They observe the angle formed using properties of the unit circle.

Students investigate gravity and engineering by participating in a slide building experiment.  In this early physics lesson, students utilize cardboard boxes to create a model of a children's slide.  Students analyze the other...
