Instructional Ideas

• Allow pupils to watch the video multiple times; then write a summary of the content presented
• Use the provided problems as board work to check for understanding and catch misconceptions

Classroom Considerations

• Video does require Internet access
• Lesson follows the pre-test in this series of eight

Pros

• The process of solving equations is explained conceptually, avoiding a memorization strategy

Cons

• Resources do not include any problem solving or real-life examples
• Video is more than 13 minutes in length, which may be a long time for younger learners to stay focused
