Instructional Ideas

• Create practice problems that align with the guided practice in the videos
• Use graphic organizers or notes that include different colors or shading to set apart the rows and columns

Classroom Considerations

• Video best fits as a review of matrices

Pros

• Teaches the concept in one video and reviews the three practice problems in separate videos
• Includes an explanation for why multiplication of matrices is not commutative

Cons

• Videos are not engaging or memorable
