This is a powerpoint presentation that is intended to be an introduction to simplifying radicals when the number under the radical isn't a perfect square.
The slide has animations but no text as it is intended to be used along with a teacher lecturing/discussing with the class.
The method shown has students consider the possible factorizations of the number to find the one that includes a perfect square. I start with a short "proof" by showing how the method works with a number that _is_ a perfect square. Several examples are worked through, including one with different possible factorizations that each lead to the same answer. The last slide has some examples for the class to try with a large visual timer on the screen.
