Reflection: Developing a Conceptual Understanding Using an Area Model to Multiply Binomials - Section 2: Investigation


I find that my students, many who have significant interruptions to their formal education, really connect with using an area_model to multiply binomials as opposed to the more conventional FOIL method.  Many of my students have been exposed to FOIL in the past, in other academic settings, but almost all of them switch to using the area model once they learn it.  I also like how it previews factoring for students.  I find it's a lot easier for them to see why they are looking for two numbers that multiply to the "c" term and add to the "b" term when they have area model right in front of them.

Using an Area Model to Multiply Binomials

Unit 4: Quadratics!
Lesson 6 of 18

Objective: SWBAT use symbols to express the areas of rectangles created by altering squares with sides of length x.

Big Idea: Who needs FOIL? Students learn to multiply binomials by using a geometric model.
