For me, the sequence and series unit is the third unit we will cover this year in Algebra 2. I like this unit, because ideally students should be pretty comfortable with linear and exponential equations already (from Algebra 1). Because of this, my assumption last year was that I didn't need to spend much time reviewing explicit (or as I called them, "function"-al equations). This was a mistake, I figured out after the unit was done. I'm making changes to prevent the mistake and timing of figuring it out.
As I am going to be trying to create and use an interactive notebook system with the students in Algebra 2 this year, I figured it would be nice to create a set of cards which I could use with this unit. My thoughts progressed and as of now I am planning on using 3 different sets of cards, one of which is a set I made for Algebra 1 + 2 last year that only includes graphs.
One of the other sets will be one in which tables and equations are to be sorted by whether they are linear, exponential or other. In this way I can get the students looking at 3 of the different representations linear and exponential equations can have.
The last set includes finite and infinite sequences. There are 40 cards and most of them are arithmatic or geometric sequences. (I debated including some non-arithmatic, non-geometric sequences and decided that an other category is a good thing because it allows me to more easily differentiate the instruction for students who need a challenge). I figure this same set of cards can be used for series as well as sequences, with 2 dice used to identify the upper and lower values for summation.
I haven't actually written the interactive notebook pages to go along with these card activities, though I do have an idea about what they will likely look like. I am hoping to get to those pages sometime in the next 2 weeks, though.
