Simplifying Cube Roots
Students learn to simplify a square root by setting up a factor tree for the number inside the radical. If a factor pairs up in the factor tree, then it comes out of the radical. If a factor does not pair up, then it stays inside. Students also learn to simplify a cube root by setting up a factor tree for the number inside the radical. If a factor is part of a group of three factors that are the same, then it comes out of the radical. If a factor is not part of a group of three factors that are

Calculus Limits: A Numerical Approach
In Calculus, the term limit is used to describe the value that a function approaches as the input of that function approaches a certain value. This video explains the two ways to demonstrate Calculus limits: a numerical approach or a graphical approach. In the numerical approach, we determine the point where the function is undefined and create a table of values to determine the value of the variable as it approaches that point. (1:45)
One-Sided Limits
This video explains one-sided limits. A limit is the value that a function approaches as the input of that function approaches a certain value. In Calculus, sometimes functions behave differently depending on what side of the function that they are on. By definition, a one-sided limit is the behavior on only one side of the value where the function is undefined. (3:02)
Calculus Limits: A Graphical Approach
This video explains the graphical approach to determine a limit. There are two ways to determine a limit: a numerical approach or a graphical approach. In the graphical approach, we analyze the graph of the function to determine the points that each of the one-sided limits approach. (3:02)
Infinite Limits: Vertical Asymptotes
This video explains when a limit decreases or increases without bound near certain values for the independent variables, they are called infinite limits. In general, a fractional function will have an infinite limit if the limit of the denominator is zero and the limit of the numerator is not zero. The infinite limit can be either positive or negative and is determined by the sign of the quotient of the numerator and the denominator. (3:23)
Continuity of a Function
This video explains the three conditions that must be met in order for a function to be continuous at a certain point. The continuity of a function only exists if these three conditions are met. (0:55)
Averages (in Algebra)
Introduction to averages and algebra problems involving averages. This video starts off with a black screen because the narrator uses it as a 'chalkboard'. This video is appropriate for older mddle and high school students.
The Giants of Philosophy - Arthur Schopenhauer - 15/18
'Arthur Schopenhauer (22 February 1788 – 21 September 1860) was a German philosopher known for his atheistic pessimism and philosophical clarity' (Arthur Schopenhauer, Wikipedia, 2009). He was influenced by Plato and Kant, and he, in turn, inlfuenced Einstein, Freud, and Jung among others. Suitable for high school students. Video consists of one still image and narration.
Homonyms (part 1) This video has Wordboy helping a child learn about homophones. In this video students are given a sentence and they need to fill in the appropriate homophone to complete the sentence. Video can be stopped, student can work through the sentences and the video restarted. End of video gives a review of what homophones are: words that sound alike, have different spellings, and have different meanings. More sentences are given with w
