Factoring Practice!

04 September 2014
Today in Algebra 2 Honors, my students practiced factoring.  Yesterday, their homework was to look through their notes and textbook to find the three hardest factoring problems they could find.  I told them they could work with friends and bring the same problems, as long as they could tell me why they thought the problem was difficult.  My students thought I was joking at first.  One boy said, “This is like the easiest homework ever!” and a girl glared at him and hissed, “shut. up. now.”.  Super funny.  Their bellwork today was to list the “hard problems” on the board.  Some of the problems they chose were from their Factoring with Symbols worksheet.

Once all the problems were on the board, we worked the problems together.  I had a few reasons for doing this:
  • I wanted the students to practice articulating why they didn’t understand something.  As a class, we talked about why a problem “looked scary”, then broke it apart together.  I kept stressing patterns.
  • I wanted them to get used to seeing challenging problems, and actually working through them.  This is a tiny baby step I’m taking to try to teach perseverance in problem solving. 
  • My students were much more focused because I was working “their” problems.  A few of them were impressed that I could factor the problems on command.  Come on guys, it’s my 4th year teaching the same course using the same textbook.  I practically have those problems memorized.


When we finished working the “hard problems”, I had my kids do a set of matching cards with a partner.  They were supposed to match a polynomial with the factored polynomial.

I also gave them dry erase markers so that they could use their desks as scratch paper.  They LOVE writing on their desks.

I like to copy the problems in a different color from the solutions when I make matching cards.  It's easier for the kids to start working when they know what they're supposed to match.

  1. I love that matching cards activity and the idea of printing the cards and solutions on different colors! We are working on formative assessment this year and this a great way to do it after teaching a lesson!

    1. Thanks! I love matching cards because they're very low pressure for my students. Also, many students that think they can't do it often do well with the matching cards. If you get a chance to try them, I hope your kids like them :)
