Linkfest for Tuesday, March 4

So many good posts lately! How will I ever remember all this good stuff?!

• Sam, on having courage, and math as a creative endeavor.
• Parametric Functions, and a rational parametrization of the circle.
• Better polar explorations. (This would even be good in Calc II, I think.)The key is to make it into a puzzle.
• And here's a puzzle approach to inverse functions.
• Determining distance traveled from velocity, from Robert Talbert, for calc I.
• Shireen has made a Where's Waldo themed worksheet to help calc students think about position, velocity, and acceleration.
• I can't watch video right now, my son is sleeping. I have to watch these classroom videos, with students debating in math class, and creating theorems.
• I don't always agree with Curmudgeon, but I'm sure glad I follow this blog. Here's a great post on requiring Algebra II.
• Malke's thinking about spatial reasoning. Here's a post she linked to, with a cute question. If we fold the paper like this, and hole punch it while folded, where will the holes be when we unfold?
• Maria Anderson likes to think about the future. She's made four predictions about technology-enhanced learning.
• Have you heard of Osmos? It's a physics game app. I want to buy it.

Eleven really good ideas in one day?! It's too much!
