The last time I taught Algebra 1, I used Step Puzzles by Naoki Inaba to introduce the idea of arithmetic sequences. I tweeted about it, but in the craziness of packing up my classroom and house to move last summer they never made it up on my blog. I was first introduced to the amazing …

I used this classifying sequences task from Mathspad (subscription required) as a quick review of the different types of sequences with my Algebra 1 students before our quiz. In this activity, students must classify each sequence as arithmetic, geometric, or Fibonacci and find the next two numbers in the sequence. We glued the half-sheet in …

I created this classifying sequences activity to give my algebra students practice distinguishing between geometric and arithmetic sequences. I also threw in some other sequences which we classified as “neither.” On top of classifying the sequence, students also had to identify the next term in the sequence. My original plan was to make this a …

I created this types of sequences graphic organizer for my Algebra 1 students to glue in their interactive notebooks. Even though Oklahoma’s standards only mention arithmetic and geometry sequences, I decided to include a category called “Neither” as well. This gave me the opportunity to expose my students to the Fibonacci sequence! In retrospect, I …

I created this graphing geometric sequences foldable to wrap up our sequences unit in Algebra 1. After working with finding rules and terms, I decided I still needed my students to wrap their minds around how the graph of a geometric sequence differed from the graphs we had previously made for arithmetic sequences. After graphing …

I created this geometric sequences formula graphic organizer for my Algebra 1 students to complete and glue in their interactive notebooks. Geometric sequences are my students’ only real exposure to exponential functions in Algebra 1.  So, I just broke down and gave my students the formula for finding the rule for a geometric sequence.  It …

I created this arithmetic sequences practice sheet to give my Algebra 1 students extra practice with writing rules for arithmetic sequences and finding various terms in the sequence. Students were given various arithmetic sequences. After writing a rule for the sequence, they had to use that rule to find the 15th term, 50th term, and …

I first learned about the DINO method for finding the nth term of an arithmetic sequence from the Miss Brookes Maths blog.  A google search led me to this free worksheet and poster set from Numero Maths (sadly the link is no longer working). I think I will get rid of the DiNO part of this next …
