High School Math Video Library
These resources cover several content areas for high school math topics. Most videos are short, intended to cover a single concept or problem-solving technique. Subheaders indicate the appropriate courses for which the videos are intended. At the bottom of the page is a video-enhanced lesson plan for Calculus.
Algebra
Video 1: Finding Slope & Y-Intercept from 2 Points
In the below video, the instructor shows how to find slope and y-intercept of a linear equation from two points on a graph. The graphics include the x-y plane as well as a visual of how to know which line has a larger slope.

Video 2: Adding Polynomials with Algebra Tiles
In this video, the instructor uses manipulatives to teach adding polynomials. For many students, polynomials can be difficult to visualize - the graphics in the video assist students with a real representation of an abstract concept. He also uses humor and

Geometry
Video 3: Congruent Triangles
The instructor uses both lecture and graphics here to show how to prove two triangles are congruent, followed by several examples of different triangles. He explains step-by-step instructions for a verbal proof, and what a student would look for in each triangle.

Algebra 2
Video 5: Logarithms Explained
This video is a little different and uses humor and eye-catching graphics to explain logarithms. It uses several practical examples and proper math notation to explain the notation for logarithms as well as how to convert from exponential equations to log equations and vice-versa.

Video 6: Domain & Range of Square Root Functions
The instructor uses a low-tech approach that is straight-forward and simple to understand. He explains how to start the problem by sketching the function, then proceeds to explain how to find the domain and range from the sketch.

Trigonometry
Video 7: The Unit Circle
In this video, the instructor constructs the unit circle for calculating trigonometric values. He also defines the initial and terminal sides of an angle, and discusses drawing positive and negative angles.

Calculus
Video 9: What are Limits?
In this video, the instructor defines a limit, and shows how to solve limits by direct substitution. He offers follow-up videos for other limit techniques and shows both a function view and a graphical view of limits.

Video 10: Volumes by Rotation
The instructor shows how to sketch and solve a solid of revolution volume problem. In addition to the math, the video also shows 3D representations of the figures to aid students in understanding the process. Multiple examples are given, with equations and notes on how to find each piece of the integral expression.
