I just spent a happy part of my evening solving this problem. Apparently there’s an easier method than the one I used. brb.

What I Did Today: Classroom Setup

The first day of school for teachers is the day after Labor Day, but I like to go in early to get things in order. I don’t like being rushed. Note: the empty boxes of paper and floating metrocard polyhedra.

Happy Pi Day!

As a math teacher and math lover, things like this make me sad and mad. It seems the purpose of this clock is to force the reader to perform a mathematical calculation.

Oh, except for eleven. I guess they couldn’t think of a mathematical expression for eleven. Let’s just write that out as a word. That’s equally as difficult.

Actually, I guess they really ran out of ideas because they used the radical of a perfect square twice: once for two and again for eight. Two cubed maybe?

Nine is not equal to three times the quantity of pi minus 0.14. That expression is only approximately nine because pi is not equal to 3.14. Rookie mistake.

52 minus x squared plus x equals ten has two solutions: negative six and seven. Oh, it’s 7 o’clock or -6 o’clock. Or maybe we can pretend it’s prior to the 1600’s when negative roots for quadratics were rejected as answers. But wait, it’s 2012.

Lastly, Tan(45) is equal to about 1.6198. Oh, I thought it was one. Well, the Tan(45 deg) is equal to one, but if units are not specified the units are understood to be radians. Advanced rookie mistake.

Come correct or don’t come at all. Props for the gamma and integral hands.

## Real Life Math: When to have tutoring?

I had my students tell me when they had free periods so I can schedule tutoring in such a way to help as many of them as possible. I have 137 students. 85 of them have H band free, 105 have E band free, and 67 have H band and E band free. How many of my students are not free either E band or H Band? **HINT**: Use a Venn Diagram.

Setting Up My Classroom

What I spent my morning doing.

**Acute Style Fact**: The polyhedron on the far right on the top shelf of the bookcase is my favorite polyhedron of all time. The greater dodecahedron.
