Why I Love Julie Reulbach and Desmos

Transformations is something I have worked at over the years to have a solid series of activities and notes to help students comprehend how they work. (Side note, maybe I ought to look back at my blog more often. I had forgotten I had put together a couple of these things.) We are in round 1 of transformations. I am working with F.BF.3, which reads Identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them. The learning target this time is: I can describe the transformation(s) that changed a graph of f(x) by replacing with f(x) + k, k f(x), f(kx), and f(x + k) for specific values of […]

#Descon16 Reflections

Normally, I don’t blog during TMC. In fact, it’s the night before we start and I really ought to be headed to bed. But I had some thoughts and connections I had made while at the Desmos Preconference. After our kickoff to the morning, we separated ourselves into groups based on comfort / ability level with Desmos (beginning, intermediate, or advanced). At first, I thought I may be a beginner plus but not quite advanced, but once I saw the document that Michael Fenton created, I realized that I was a solid intermediate. After some discussion of where to head, Julie Reulbach made the point that if I went to intermediate, I could end up helping others whereas if I went to advanced, I would be pushed and would be learning from others. I definitely wanted to be pushed a little bit, so I went to advanced and promptly figured out I was over my head. But I stayed anyway. What […]

Daily Desmos Sub Plan

A couple of days before the last time I knew I was going to be out of the classroom, @Desmos tweeted this: How many of you have #EmergencyLessonPlans that say some thing like, “Ss will visit, pick a challenge, and…” #mathchat — (@Desmos) November 13, 2013 I thought about this tweet for about a second and realized that it would be the perfect solution to my sub plan problem for Calculus. Here is what I put together for them: I was hoping for more out of my Calculus students. They pretty much went for the easier ones and only turned in two. Granted, I wasn’t there for their last period Friday afternoon class, but I am guessing that it did not take them a majority of their 50 minute class period. I would like to use this again, but I definitely need to do some tweaking. Regardless, I did want to share it. Maybe it will inspire someone […]
