# Free 3rd grade math video lessons

This is a collection of free math videos for 3rd grade, showing varied exercises for each topic. They match Math Mammoth Grade 3 curriculum but will also work no matter which curriculum you follow (in other words, the videos don't rely on you having Math Mammoth curriculum).

These videos are usable for students, teachers, and parents. You can use them...

• To learn these topics yourself (if you're a student for example, or an adult needing a refresher)
• As lesson plans for teaching these topics. Often, one video from below can be made into several lessons with students.

Please choose a topic from the list. Please realize this is not a complete coverage of all 3rd grade math, and I hope to add to the collection in the future.
