How to multiply binomials using a box!
Wednesday, February 10th, 2010Many people find this more visual and intuitive than FOILing.
I split the video into 8 brief parts. Each part features one practice problem, fully explained and demonstrated on the whiteboard.
If you, your family, or your friends would like to see me make an instructional video about a particular math topic or type of problem, leave a comment to nominate your math problem for its very own video!
And if you like the video, please feel free to click on the “heart” to show that you “heart” it. <3

These videos are great! I’m so glad to see an alternative to FOIL as it is a limited use concept. You’ve explained things so well and I love the visual style.
Wish I had seen this before I blogged about our FOIL video.

April, it’s so nice to “meet” you! Thanks for stopping by. I’m really excited to share this idea because I think it’s an easier way for some people to learn how to multiply binomials. Thanks for sharing your blog post, too!
