Here's a Lesson Hook

I'm teaching a mini-unit on conversions between units right now in my Algebra classes. This means converting between U.S. units, metric units and conversions between both systems. For example:

  1. Mount Everest is 29,028 feet tall, which makes it the tallest mountain in the world. How many miles tall is this? How many inches?
  2. For death penalty cases by lethal injection in the United States, criminals are given 5 grams of sodium thiopental. How much is this in kilograms?
  3. If you're speeding down the highway in the Dominican Republican at 100 km/hr, how fast are you going in mi/hr? Compare this speed to New York State's highway speed limit of 65 mi/hr.
In my limited experience, this seems to be a topic students tend to enjoy and remain interested in because it's more relevant than other topics. Today, I planned on introducing the metric system to my students, who for the most part have never thoroughly learned the system due to this country's obsession with the old system. I choose to blame this lack of conversion on the NFL for basing the entire game off yards.

After I made some general announcements, I pressed next on my wireless clicker to move forward to the next slide, creatively titled, "The Metric System." The slide was blank for now: I use custom animations. In my mind, I wondered, "how the hell do I present this shit again and make sure they stay focused?"

See here's the thing. Today was a rainy day, and in our country's education system, that means most students in inner-city schools consider this a holiday. Can you imagine? This is such a great deal. I guess I missed the Groupon on that one.

So I'm standing in front of the class with a meter stick over my shoulder, and I begin to ask:
"So does anyone know what the Met..."
Holy shit! An idea. So simple. So easy. How could I have missed this? Should I say it? Eh, fuck it, I'll say it. I decide to rephrase my question:
"... So when someone wants to buy or sell drugs, what unit of measurement does this person use?"
Okay, that was quite a gamble, I admit. But this is a transfer school, and if you can't be real, you won't last. As expected, I hear:
"GRAMS!"
 "Yo, you gotta weigh that shit and them weighing machines only tell you in grams, so you gotta convert too. Shit is complicated, I seen it done."
"My n****, when you buy that shit, you gotta come home and weigh it too so you know you ain't gettin' ripped off!"
TMI? Maybe. But this was one hell of a hook. And they actually stayed focused the entire time.

Please report to the principal's office.

Haha, funny thing is, during one of my Algebra periods today, my principal and assistant principal walked in for a brief informal classroom observation about two minutes after I asked the drug question. Wonder what they'd say...

Oh, and as always, thanks for the Twitter-bump.

What do you want me to tell the kids when you're gone?

Admin also missed the conversation in my class about getting rich off of worm poop.

metrics are lame... we won't need to measure things once the apocalypse happens

On My Visit to My Old High School

I had the incredible opportunity to visit my old high school while I was in Chicago last week.  This was something I was really looking forward to; I was worried I wouldn’t have enough time to cram in a visit. I wanted to not only visit my old teachers, but also to walk around the hallways aimlessly and remember what it was like to be me eight years ago. It still blows my mind that I’ve been out of high school for that long. Okay, fine. The voice of accuracy in my head desperately wants me to clarify how long it’s really been. Technically, I had gone back to visit a few of my teachers shortly after I graduated high school, but I choose not to count that as a “proper” visit as I was still in college and coming back home quite often. It’s not like I was living out of the state as I am now. So it doesn’t count, okay? So Wednesday morning, I walked into the visitor’s entrance at gate 3 and received my visitor’s pass for the day. It was odd because as a student, I never en

We Need to Talk About Tenure

The idea and privilege of "tenure" in public education has garnered a lot of attention as of late. Most people who have never worked in education a single day in their lives seem to feel that tenure is unfair and teachers should work under the same expectations that other "regular" and hard-working Americans work under. At least, that's the narrative being presented in the media. Three years ago, I would have agreed, but I didn't know any better. At the college and university level,  tenure  is difficult to obtain and can take 4-8 years. Correct me if I'm wrong here, but from what I think I know, the candidate usually needs to have published some sort of research and have demonstrated a strong teaching record, among other things. Before becoming a high school teacher, I understood why tenure was necessary at the college and university level as it protected academics when they published work that went against the mainstream, and thereby prevented profes

Resurrection

I'm back.  It's been nearly a year since I've last written on Yo Mista!  A lot has changed personally. Yet nothing has changed professionally. And I guess that's why I've been so uninspired to write.  Over the last year, my professional life took a backseat to my personal life. When the dust settled, I realized I didn't want to write  Yo Mista!  anymore. I still felt passionate about my work, but I was somehow uninspired. My day-to-day at school over the last year hasn't changed. I still teach over-age, at-risk students at an alternative high school. Everyday, crazy shit happens in my classroom. Everyday, a student either feels supremely connected to me and my content or feels without direction and completely out of touch with education. My students and I still keep each other on our toes. The only problem is, I'm getting jaded.  This is my fifth year of teaching at-risk youth and I'm getting tired of seeing students arrive to school hig
