Math Posts: 108 Location: Henry Clay | Been a long time since I've gotten "excited" over factoring.....But I am now! I have always used FOIL for multiplying and mostly guess and check for factoring. I saw the box method on here for Ch 4. So I showed my Alg 1 kids both FOIL and the box method. I let them choose which they preferred. Well, when test time came, the kids who used the box did SO much better than the kids who did FOIL....hmmm must be something to this! I went back and taught/made everyone do the box method. Then I research how to do factoring with the box. Hence the x-box method. So far the kids are doing well!!! Here is a link to a powerpoint to explain the process. jaegeralgebra.wikispaces.com/file/view/Jaeger.ppt Oh, before I started this, I spent a whole day doing x puzzles with them. They are on the ilovemath site under Algebr, polynomials and factoring. They are called sum and product pre-factoring puzzles.

Math Posts: 24 Location: LTMS | For non-monic quadratics (a>1), I have students find the factor pair for a*c that has a sum (or difference, if c<0) of b, then split the "bx" term into these two parts, then use grouping. This seems to be much easier (and shorter) than trial-and-error. | ||

Math Posts: 108 Location: Henry Clay | xbox is a version of splitting the middle term....It's just very visual! We even started on day one with having a leading coeffiecient. | ||

Math Posts: 76 Location: PL Dunbar | I have been using the box method as we refer to it, for the last 5 years or so, the kids love it, it really helps them visualize the concept of factoring and it works for everything. Love it! | ||

Math Posts: 30 Location: Lafayette | I really like this concept...I have heard of the "x-box" method before (by some version of that name) but have never seen it used. The powerpoint was really helpful in illustrating the method. Thank you for sharing! I may incorporate this in my factoring lesson if not I'll definitely use it next year! | ||

Counts on fingers & toes Posts: 15 | Oh wow! I've never heard of this x-box method, and here I am a year later looking at the topic. I could've used this method this year, but hadn't checked out all the posts prior to now. Too bad, but it looks like a GREAT method for next year! By the way, I love MILC-just wish I had been using the forum sooner! | ||

Math Posts: 9 Location: SCAPA | I have seen students use the x-box factoring but have never 'taught' it. I do plan on beginning my unit this year demonstrating this method and analayze whether students are more successful. I have a feeling they will locate factors more quickly. Thanks for the link. | ||
