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

Squeeze Theorem
Mr. Khan offers this video of the intuition (but not a proof) of the Squeeze Theorem. Mr. Khan uses the Paint Program (with different colors on a black screen)Â to illustrate his points. Sal Khan is the recipient of the 2009Â Microsoft Tech Award in Education. (07:37)
Algebra Word Problems - Math Help
In this video, which is for middle school students and older, the instructor uses a white board to demonstrate. Students learn to solve "number" word problems, such as the following. One number is four times as large as another. The sum of the numbers is 45. Find the numbers. Since the first sentence states that one number is 4 times as large as another, the numbers can be represented as x and 4x. Since the second sentence states that the sum of the numbers is 45, the equation can be set up as x
