![]() Explain that the goal for the next few classes is to be able to graph similar graphs. Have a couple student present a figure they like to the class and begin asking simple question like: Why did you chose this picture? Which slides did you use to get here? What did you observe of this sketch? What happens to the equations when you move one of the slides? After the last students shows their figure, bring the class together. Using the sketch pad above, have students create different figures by moving the blue, green, and red slides. Since technology is advancing at a fast rate using an online sketchpad such as,, allows student/anyone to explore without much thought. Let’s say the teachers is just introducing parametric equations for the first time to his/her students. ![]() Graphing calculators and online sketch pads can allow students to be able to visually see how parametric equations look like. How can technology (YouTube, Khan Academy, Vi Hart, Geometers Sketchpad, graphing calculators, etc.) be used to effectively engage students with this topic? Note: It’s not enough to say “such-and-such is a great website” you need to explain in some detail why it’s a great website. Her topic, from Precalculus: graphing parametric equations. This student submission comes from my former student Perla Perez. I plan to share some of the best of these ideas on this blog (after asking my students’ permission, of course). Instead, I asked my students to think about three different ways of getting their students interested in the topic in the first place. In other words, the point of the assignment was not to devise a full-blown lesson plan on this topic. ![]() ![]() In my capstone class for future secondary math teachers, I ask my students to come up with ideas for engaging their students with different topics in the secondary mathematics curriculum. ![]()
