Instructional Ideas

• Use the lesson as an extension for your upper-level pupils
• Vary the size of the polynomials and order of the operations when practicing

Classroom Considerations

• Pupils should be comfortable with both multiplication and subtraction of polynomial expressions

• This video is hosted on YouTube

Pros

• The use of color helps to follow the terms and steps of multiplication

Cons

• Shows only a single example, which isn't enough to show variation in the presentation of the problems
