Insidemathematics.org

Like LearnZilion, insidemathematics.org contains videos that can help teachers expand their lessons. Insidemathematics is a great classroom resource, as the site contains videos for a variety of mathematics concepts. Here, a teacher can find videos that help to engage students, help build a mathematical environment as well as help lesson planning. The videos on the website range from launch's as simple as number talks, to more complex videos based on deep mathematical learning. The site is a great resource for useful and accurate math videos, but is also a useful resource for finding performance assessment tasks, mathematics tools, and supplemental mathematics material.

KHANACADEMY

Khan Academy is a great resource for instructional videos. While the website above offer videos that are specifically supplementary resource for teachers, Khan Academy's audience is the student, however, while a teacher should not rely on this video platform to teach material, it is useful in order for review purposes, as well as gives students examples of similar math problems they may encounter in class.

The Khan Academy website is more advanced than the two above as the content ranges from simple mathematics to college mathematics, along with other domains such as chemistry, biology etc.

While many know about the student side of Khan Academy, Khan Academy also offers a teacher's, where teachers can find useful lesson plans, as well as receive helpful hint of how to use videos as assignments, and align videos to classroom objectives.
