**Is it possible for standard deviation to equal zero?**

Such a great question : Select only four numbers from the numbers 1 through 10, such that the standard deviation is the smallest. Repeat to find a standard deviation that is the largest. Is there more than one choice for each set? I love this question. I...

Well, I had an epiphany over the weekend about using my whiteboards. So I had it all planned out for Calc. Today I gave them problems from each problem set (the old HW pages that we now do in class) and had them put them up on their whiteboards. I loved ...

**How I spend my Saturdays**

Some might think I'm a little crazy with all the ideas that I am already employing. So the fact that I spend Saturdays traipsing around Southern California attending conferences to learn even more stuff is simply insanity. Let's face it: I probably passed...

**Calculus around the room and "the Statistics talk"**

I cannot express enough how awesome it is to have the whiteboards (mounted all the way around) in my room this year. Ask me again in a few months when I have possibly had to purchase the markers (although I am making that a requirement for every student in ...
