### Fail Friday...on Saturday

I had been meaning to get help on this activity a while back, so Fail Friday seems to be the perfect opportunity for this.

Anyway...somehow I managed to totally suck at explaining intercepts this year in Algebra II.  Even after an entire semester with these kids, when I say, "What's the y-coordinate of an x-intercept?" all I get is *chirp, chirp, chirp.*

I wrote up this literacy strategy, that I was quite proud of.  I felt like they finally understood the algebraic definition of an x-intercept, and not just the geometric definition (i.e., I want more out of them than just "An x-intercept is where the graph crosses the x-axis.").  But...the next week I felt like we were back to square one.

Help!  How can I help them understand and generalize the concept of an intercept?  I especially want them to understand how factors and zeros are related.  What have you tried that you have had success with?  Class composition is juniors and seniors.

1. One thing I found at a conference were these "link sheets". They were just 1 equation per side of a sheet, but the sheet is divided into 4 (or more) parts: equation (factoring?), graph, table, and verbal description/questions. The students have to get all 4 parts of the page to match.

I think I've got an example here:

If you want more, the speaker at the conference has a whole semester's worth of them (and I've created a handful), and I can send them to you!

1. Thank you! Is this kind of like a Frayer model?--> http://www.worksheetworks.com/miscellanea/graphic-organizers/frayer.html
