I've got a training session coming up on math teaching and, since the participants will be coming from a wide range of backgrounds, I've decided to partially flip the class and put together a few videos reviewing some of the more basic concepts involved in the example lessons so that all the participants can start from roughly the same place.

If you happen to be one of these participants and you're wondering if any of these review videos are right for you, take a look at the following questions:

Are you still a bit confused by the different forms of fractions (mixed numbers, decimals, etc.)?

Forms of Fractions

Not sure how long division works or why we sometimes get repeating decimals?

Long Division

Forgotten how to add, subtract, multiply and divide fractions? (or make that multiply, divide, add and subtract – but we'll get to that later)

Operations on Fractions

Not quite clear on what that log key does on your calculator (not to mention all of the other ones)?

Not sure how to find the prime factors of a number?
