My students have always had a hard time factoring, probably because of the multiplication and backwards thinking. This year I started our unit with a whole lot of thinking and a whole lot of hands-on - with cereal!

**Intro to Factoring**

In this trinomial, we needed to multiply to 12, so students counted out 12 pieces of cereal.The idea is that students will work their way though different arrays of cereal that make perfect rectangles and write down the side lengths.

As they worked their way through the different combinations, students wrote their pairs in the box and looked for a pair that add to B.

When I finally introduced the first actual trinomials, I heard a lot of, "This is light work!", which I have found to mean, "This is easy?". I loved it! Once the foundation was there, moving to negative numbers was a lot easier.

A fun way to summarize a factoring unit is with a factoring pennant. Students get to color while also showing their understanding of factoring quadratics. The finished products are also a great way to decorate your classroom.

Outstanding hands-on approach! I love this!

ReplyDeleteThanks so much! I'm pretty geekily excited about factoring this year! :)

DeleteI cannot stop reading all you are saying! I am so excited about all you are sharing.

ReplyDeleteCannot thank you enough!!!

Paula, you are so kind! I hope you have a wonderful weekend:)

DeleteLesson planning for the 5 days I am allotted for factoring and this is definitely planned for day 1!

ReplyDeleteFive days! I WISH I could get through factoring in 5 days. It would never, ever be possible. Do you feel that is enough time?

DeleteWhen C is negative, I plan to explain that we will subtract the side lengths to get B. One of these days I'll actually write a post about the lesson! :)

I'm going to try this tomorrow, super excited. Love the hands on approach! I also teach special ed Algebra 1. I couldn't find the powerpoint but that's ok :) Thank you for the idea

ReplyDeleteUgh, why did I write "Powerpoint"? And I just now noticed how I linked it wrong! It should be fixed now. THANK YOU for letting me know! The Prezi was really helpful to my students. I hope they "get it" with the cereal!
