### Kicking Off Sequences in Algebra 1

My Algebra 1 students have just started their unit on sequences.  This is my first time teaching sequences in Algebra 1 because it used to be in the old Algebra 2 standards.  For the past four years, I have taught sequences and series in Algebra 2, but I feel like I need to take a different approach with my Algebra 1 students since we're only doing sequences.

We kicked off the section with a set of definitions and examples.

I took this as an opportunity to introduce my students to the Fibonacci sequence for the first time.  We talked about the Fibonacci sequence on Friday.  On Saturday, I was walking through the Science Museum of Oklahoma, and I saw the Fibonacci sequence in a display.

I took a picture to show my students because I'm not sure that they believed me when I told them how famous the sequence is.

Next, I gave my students 21 sequences.  Students had to find the next term in each sequence.  Then, they had to classify the sequence as arithmetic, geometric, or neither.

I was looking through the resources available from MathsPad, and I found this puzzle in their sequences section (subscription required for this specific resource).  This puzzle has students find the next two terms in a sequence and classify the sequence as arithmetic, geometric, or Fibonacci.  It was fun to have the Fibonacci Sequences in this puzzle since the practice sheet I made didn't have any Fibonacci sequences.
