The resource at the bottom is a formula chart for geometric and arithmetic sequences and series. The third resource is an arithmetic and geometric sequence and series game. Since arithmetic and geometric sequences are so nice and regular, they have formulas. The second resource would be a great follow up after teaching arithmetic sequences. I’m working on the geometric sequence activity now and hope to finish in a week or so. I’ve attached a couple more of my resources. I wanted to create something that students could learn from and see how these patterns are involved in real-life situations. When I was creating this resource, it really stretched my thinking. Some of the examples I used above are in my Arithmetic Sequence Activity seen below. Students need to know that their math is real and useful! I hope this encourages you to use some of these examples or make up some of your own. It’s really fun to create these problems. I hope I’ve given you plenty to think about. When you are finished reading this post, please consider filling out this feedback form called: Understanding Our Visitors. ![]() I’m happy for you to use these situations with your classes. Yes, but I want visuals! I also did not want the situation to be a direct variation or always positive numbers and always increasing or positive slopes.īelow are some of the situations I’ve come up with along with a picture. 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. My recent thoughts have been about arithmetic sequences. I’ve also tried to catch the situation in action, but it’s not always possible especially since sometimes I think of an idea while driving or when I’m falling asleep at night. I’ve made it a goal of mine to find real-life situations. When I was in college and the earlier part of my teaching career, I was all about the math… not how I might could use it in real life. One of my goals as a math teacher is to present real-life math every chance I get.
