Who's the best for the job? A modeling instructional activity asks your class to analyze job applicants before deciding who to hire to best get the work done. Pupils work in groups to find the best combination of workers that will be...

Climb up the staircase of engineering knowledge. After watching a video of a carpenter measuring out steps for a set of stairs, pupils learn about the terminology and regulations involving stairs. They see how to use a rule of thumb when...

Breaking the law isn't possible when talking about the Law of Sines. Individuals learn to apply the Law of Sines to solve problems involving triangles. They also learn to derive the Law of Sines.

In this video, Sal shows how the sine and cosine of an angle are defined on the unit circle. He inscribes a 30-60-90 triangle in the unit circle and explains how one can use SOH-CAH-TOA to find the coordinates on the circle.

If your math students are having a hard time with graphing and slopes, this video could be a great resource as they prepare for the SAT. Sal takes care in explaining his thought process, making sure where to note different strategies to...

Sal's goal in this video is to "familiarize ourselves with the x, y-coordinate plane." If your pupils have blank expressions when you present them with graphing problems, this video will be a great help to clear up the basics.

Highlighting the basics of working with angles, this resource could provide a sound introductory activity for students who are beginning to learn about angles. Eager mathematicians will be introduced to the terminology associated with...

"Demystifying" an often mysterious problem, Sal demonstrates some tricks for considering exponents intuitively, rather than working them out each time. He first takes viewers through positive exponents and works up to negative exponents,...

In this introductory video, Sal defines polar coordinates and using basic trigonometry identities and the Pythagorean Theorem defines the relationships between Cartesian coordinates and polar coordinates.

Students examine digital images and how satellites orbiting Earth send information and pictures to Earth over the Internet. They use a digital camera to put pictures on a computer and decode a satellite image from space.
