    This is the first part of a lesson on multiplying fractions, which can be complicating to students at times. A number line is used to explain what it really means to multiply fractions. The video also shows how to multiply fractions across the top and across the bottom.

    I really think my students will like this video. It will be great to use as a review for material. Having the "small" teacher is attention getting and the examples are clear and easy to follow.

    This website is an excellent and engaging way to help students with all levels of math. I love it for myself (as a University student) and for my children.
