This post will short, simple, and to the point because that’s all my wedding planning frazzled mind can handle. 10 days to go. 😀

My Algebra 2 students recently started our next unit on sequences and series. To kick things off, I made a foldable that summarizes the differences between arithmetic sequences, geometric sequences, and sequences that are neither arithmetic nor geometric.

After going over these definitions and arguing about the pronunciation of “arithmetic,” we moved on to a color-coding activity.

Students had to create a key for the color coding activity by coloring the words “arithmetic,” “geometric,” and “neither” at the top of the page. Then, they colored each sequence (usually just highlighted) to match its type. Finally, if it was arithmetic, they identified the common difference, and if it was geometric, they identified the common ratio.

An Interesting side note my student told me earlier when I was teaching about arithmetic: when you have a word that is both a noun and an adjective, the accent is on the later syllable when an adjective. I will have to look it up, but she had coincidentally just read about it. Good luck and congrats!
