I recently found this amazing website called Kahoot!  Kahoot! is a game based classroom response system.  You can create your own quizzes, surveys or discussions and your students can access them on their device.  It's completely web-based so it works on all platforms and the best part is it's free!  Don't have time to make your own quiz?  Browse the over 30,000 public quizzes to see if there's one that will work for you.  I made my own Kahoot! over finding area of oblique triangles and my students LOVED it.  Once you create your own account, you can play my Kahoot! by clicking the link below:

I just discovered this amazing site called. Flippity.  You can use a Google Docs spreadsheet to create a set of virtual flashcards!  Here's a set I made:

How cute is that?!?

This is another activity we did to reinforce trig graphs.  It was fun, the kids loved it, and I did it on Digital Learning Day, so that was a plus!  I originally only planned on doing it in my Pre-Calculus classes, but my AP Calculus kids heard about it and insisted on doing it during their class, too!

*UPDATE - the day after we did this was the first day of the Winter Olympics, so I had my students chart the biorhythms for several different athletes. We're going to monitor how those athletes perform during the Olympics and compare their actual performances with their biorhythms.

Here's Shaun White's biorhythms for February 2014.  The red line marks the day he got 4th in the half pipe.

Ferris Wheel Math

I'm having my students relate what they've learned about amplitude, period, phase shift and vertical shift to a real world scenario involving ferris wheels.  I started  by having them read chapter 15 of the book, The Joy of X which I've blogged about before.  It's a chapter about the ubiquitousness (is that a word?) of the sine curve.  It's a great read!  We then focused in on the example of the Ferris wheel that he gives in the chapter.  I started by working through the first problem on the worksheet with them.  I then turned them loose to do the card match and work the second problem.  The conversations they had and the observations they made were amazing!  And I love love love the card match - it really forces them to see the connection between the graphs, the equations, and the descriptions of the Ferris wheels.  One of the graphs doesn't have a matching equation, so they have to write that equation themselves, and two of the descriptions get used twice, which brings up a great conversation about how that can happen.  I loved this activity!

Note - I didn't realize that the problem was in meters, so on the last question you can either ask them for meters/min and km/hr or you can have them change meters to feet in the problem.  Sorry about that!

Basic Integration Rule Foldables

Foldables I made for Basic Integration rules.  I had a mistake on the power rule, but I fixed it in the digital file posted below.  Before I gave them these, I had them intuitively find the integrals of some basic functions.  They were able to figure the power rule out on their own, which was awesome!

Graphs of Sine and Cosine Foldables

Foldables I made for graphing Sine and Cosine.  I'm not completely happy with them, so I'm sure I'll modify them for next year.  I'd like to add a description of what amplitude, period, phase shift, and vertical shift actually are in terms of how they're represented on a graph, not just how to find them from an equation.
