If you can multiply binomials, you can factor trinomials! This is the premise for a lesson on factoring. Pupils look for patterns in the binomials they multiply and apply them in reverse. Examples include leading coefficients of one and those with GCFs.

Instructional Ideas

• Use board work and pair share strategies to allow for frequent checks for understanding
• Include examples that do not factor to encourage comparisons to problems that do not allow for the pattern

Classroom Considerations

• Individuals should be able to multiply binomials prior
• The second installment in a series of 26

Pros

• Connecting factoring to multiplication of binomials gives learners an understanding of the process rather than simply memorizing steps
• All handouts, keys, and a detailed teacher guide are included
• An exit ticket is included

Cons

• None
