In this video, we go over how to find the Least Common Multiple, or Least Common Denominator, within the context of fractions. We use Least Common Denominators in order to add or subtract any fraction, no matter how different the denominators may be!

In this video, we go over how to add and subtract fractions, beginning with visual models of fractions that help us understand how to add and subtract fractions with the same denominator. Fractions are just slices of pizza!

In this video, we go over how to find equivalent fractions using two methods, first by skip counting with fractions and second by using multiplication and division following the rule, "whatever you do to the top of the fraction, you must also do to the bottom.” Then, we apply our knowledge of equivalent fractions within a few useful contexts, such as adding and subtracting fractions with different denominators and simplifying or reducing fractions.

In this video, we go over how to add and subtract fractions, beginning with visual models of fractions that help us understand how to add and subtract fractions with the same denominator.

Then, we move through a series of skillsets necessary to add and subtract fractions with different denominators, including: 1) skip counting with equivalent fractions; 2) following the rule "whatever you do to the top of the fraction, you do to the bottom," in order to find equivalent fractions; 3) how to reduce or simplify fractions; and 4) finding the Least Common Multiple and Least Common Denominator.

We end by bringing all of these skills together in order to add or subtract any fraction with any other fraction, regardless of how different their denominators are!

In this video, we cover the Properties of Logs: the Product Rule, the Quotient Rule, and the Power Rule. We then apply these properties in order to expand logs as well as to solve algebraic equations that include logs.
