Math = Love: Sequences and Series Foldables & INB Pages

Sequences and Series Foldables & INB Pages

One of my last Algebra 2 units before state testing was arithmetic and geometric sequences and series.  Our students are given the formulas for the nth term and the sum of the first n terms, but they are given no explanation for what each variable represents.

So, I like to spend an entire class period discussing what each variable represents.  Then, we look at word problems and label all of the information with the correct variable.  The kids hate it, but it really helps them in the long run.  This year, I had a handful of students who decided to just tune out this entire explanation.  Well, to be honest, they tuned out most of what I said this entire year.  And, their test scores certainly reflected that.  :(

By now, you know that I love foldables.  I adore foldables.  I'm pretty sure I think and lesson plan in terms of foldables and graphic organizers.  There are some foldables I make that are just meh.  Then, there are the foldables that I can't wait to show my kids.  The ones I'm about to post belong to the latter category.

I think these are pretty self-explanatory, so I'm going to post the pictures without much commentary.  If you have questions about anything, please ask!  I've uploaded templates for the formula foldables at the bottom of this post.  Enjoy!

  1. Do you teach your students the recursive formulas for sequences?

    1. I haven't in the past because they weren't tested on our end-of-instruction exams. I need to look into if they are required by CCSS for next year, though.

  2. Do you teach the sum of infinite geometric series? Just curious. Love your blog. I have used so many of your ideas and downloads for my Algebra II Interactive Notebook. Thanks so much for being willing to share!

    1. Our Algebra 2 curriculum does not deal with infinite series.

      And, thanks for reading my blog!

  3. Hi Sarah, thank you so much for all your ideas! I've been stealing so many of them! I was wondering how you'd find formula for sequences that don't exactly fit into arithmetic or geometric formula, like 1, 3, 6, 10, 15,... ?
