Just like my Algebra 1 class, my Algebra 2 class is looking at the end of the quarter, year, distance learning, and chapter 10. A test just doesn't feel right. So I have decided to have the students complete a project based on sequences. There are so many great things that they could do, I have found it difficult to pick just a couple. I have settled on 5 projects, the students will pick one to do that interests them. The projects are: Dragon Fractals Patterns on a Grid Serpinski's Triangle Spirolaterals Visual Patterns I had a sixth project, Artwork Copycat, but decided to not give it to the students. In the end, I didn't feel like it analyzed the sequences enough. Dragon Fractals: I first came across this idea looking at the wonderful math art challenge website by Annie Perkins. I was intrigued by the paper folding and how you could develop the fractal by drawing on the previous iteration. I played with it for days, even doing it in spare moments during my zoom lessons. I hope that some of my students will find it just as interesting. If we were in class, I would love to explore the connection between the paper folding and drawing the iterations. But, since this is more of an independent project and I don't have them captive in my classroom to interact with, I left that part out. Patterns on a Grid: I first came across this idea at an art museum in Wurzburg, Germany where they had an amazing math art exhibit. The picture above is a number grid that starts in the middle and spirals out. The colored blocks are prime numbers. It did not occur to me to do this with other patterns until I was thinking about doing these projects. I had a start to a project with this idea when I stumbled upon Megan's Sprials in Annie Perkin's math art challenge. The rest, as they say, is history. It is quite interesting how the layout of the number grid and the coloring of the pattern can give a design. I highly recommend playing around with this. Serpinski's Triangle: Who doesn't love a good session with Serpinki's Triangle. It is such a fun fractal and lends itself so well to sequences. I love the idea of doing the 3D version of it and I really hope I have a student or two that will do it. I am also excited to sneak in a little bit of Pascal's Triangle. I did a different version of the 3D card with a class on Valentines day a couple years ago. Instead of straight lines, we did the top part of hearts. (I am secretly hoping to receive a card or two from my students). Spirolaterals: Have I mentioned Annie Perkins' website with math art challenges? Well, this one comes from there too! I actually saw it first when Annie tweeted about it. Of course, it screamed sequences and I had to include it. It was fun to play around with the idea. I am hoping to play around with it more after school is out. Visual Patterns: It wasn't that long ago that I was visiting with some teachers and they said that every math teacher should know who Fawn Nguyen is. Well, I didn't. So I figured I should find out, and now here I am, a fan girl. One of the things Fawn has brought to all of us is her visual patterns website. When I first looked at it, I didn't do anything with it because I didn't now what to do. After attending Fawn's workshop, I have become an avid user of visual patterns. To start the sequence chapter, I had my students do many visual patterns and then used them to introduce notation and concepts of arithmetic and geometric. It also helped us with being able to find the expressions. It seems fitting that one of the projects is playing with visual patterns. I am especially excited for this project because of the fun I had with my daughters creating a tiktok. Between the quarantine and being 13 years old, it can be tough to find things that my oldest daughter and I can enjoy together. We had so many laughs creating the video, I am hoping my students will enjoy doing something similar. Artwork Copycat:
And then there is the one that didn't make the final cut. Which I am somewhat sad about. In 2016, I went on an amazing trip to Germany. It was a week-long school for math education researchers. My cup was filled from so many spouts: teaching math, traveling to Germany, exploring another culture, and visiting with math teachers from so many countries. One of our activities for the week was to visit a math art exhibit. Looking back on pictures, there were two art pieces that could be used to explore sequences. I am especially intrigued by the bright colored geometric design. Once you start exploring it, you see that it is a geometric sequence with a common ratio of 2. Trying to recreate it proved to be a fun, artistic challenge. I chose not to include it just because it wasn't quite as much sequence work as the rest and it didn't feel as rigorous as the others. I really want the projects to have the same amount of work and "value". That about covers it all. Please feel free to use any of these projects. I hope to save someone out there some work. Wishing everyone a good ending to the 2019-2020 school year.

Thanks for sharing these. I am going to use them this year in my Algebra II.
