Grade 8 Math Video Lesson Summaries

Each video highlights key concepts and vocabulary introduced in one or more lessons within the unit. These lesson videos are based on the Lesson Summaries found at the end of each lesson.

You can use these videos to support students in several ways:

Reinforce key concepts and vocabulary introduced in class.
Provide students with a resource to review and check their understanding.
Encourage students to pause and reflect on key moments, predicting what comes next or generating their own examples of vocabulary terms (the bolded words).
