### How Math Must Assess: A Review

I’m implementing Dan’s grading program, with some minor variations. I’m finding it to be almost all positive: Even after 5 years, I’d still have grading guilt. That has gone away, because I know that my kids are going to have a chance to prove themselves again. Stretching the assessment out over weeks, rather than on […]

### An experiment I’m not ready to try

A bit of a livejournal post I ran by mentioned a teacher how put up a “Do not eat the kleenex” sign as a lark, and the inevitable result. If nothing else, it should make us very aware of the potential for a huge gap between our intent and effectiveness in developing our classroom environment, […]

### Algebra Stumbling Block

I’m doing a bad thing. Some of my algebra kids are stumbling over fractions. They’ve been befuddled by them for 4 years, and freak out when they see them. So, I’m teaching them some very basics. 1) Multiplying a fraction and a whole number: Divide by the denominator, times the top. Aka !http://l.wordpress.com/latex.php?latex=\frac{\times}{\div}!. 90% of […]

### Warm Up Question 4

This is a bad idea, but I’m going with it anyway. On what date is “International Talk Like a Pirate Day” celebrated?

### Teaching Proofs – My Plan

I’m teaching geometry this year. It’s my first time since student teaching to do this, so I don’t have a whole lot of experience with it yet. Proofs are introduced in geometry. There are two whole chapters on it in our book. It seems that, because of the way that standards are written, that they’re […]

### Political Pain

I like our new principal. I like the ideals of our partnership. I like the stuff they promised us. But, they’re finding that they can’t deliver. The district has taken a “You want to show us how to make it succeed, go ahead, but we’re not doing your work for you” attitude, and the mayoral […]

### Warm Up Question 3

What is the state with the most people per square mile? As a side note: This feature already paid off in spades. My 5th period is somewhat rowdy, and takes somewhere between 3-5 minutes to settle down and work, depending on the day. All of my other classes have pens moving on paper before the […]

### Forwards and Backwards redux

So that lesson on multiplying negative and positive numbers still worked great for my algebra kids, understanding wise, even if they looked a little nonplussed at the end of it1. As a recap, it goes through various combinations of video of a student walking forwards, or backwards, and then running the video forwards and backwards. […]

### The Chair

As I go through my classroom expectations, one of the them is that they leave my stuff alone. The stuff I’ve got in my room is stuff I need for teaching. A lot of it, I spent my own money on. If they mess with it, they’re not messing with the school, they mess with […]
