The math criteria:

- Use at least 3 trigonometric functions
- Each function must have at least 2 periods
- There must be at least 2 shifts (vertical or horizontal)

Students working with Desmos in the Math Lab |

I took a day to let them play on Desmos. This was fantastic because they were able to see immediately what their transformations did to each function, without having to graph each function fifty times by hand. Also, I showed them how to restrict the domain of their functions, which taught them a teeny bit of programming. I feel that using math to understand technology is one of the greatest things I can teach my students. So a day in the Math Lab to play with trig functions was well worth it, in my opinion.

I let my students vote on the Most Creative Award. Here's their winner from 1st hour:

And from 4th hour:

Each winner got a gift card to Target in the approximate amount of $3pi ($9.42). And, no, when I asked for that amount, the cashier's face was not nearly as disconcerted as I was hoping.

But the kids laughed. And that's what matters.
