Mission Accomplished

Cohort 7, we’ve made it. Like the original Apollo astronauts, we started full of enthusiasm, though not exactly knowing where we were heading or how it would turn out. https://giphy.com/embed/vooluv4uvvi8g via GIPHY OUR JOURNEY Course 1 had us consider our network and reach out to each other to help it grow. We learned about responsible use of technology and social media in Course 2. Then Course 3 brought us both Zen and CRAAP Design Principles. And we SAMR’d our lessons and considered the what, why, and how of our profession in Course 4. And here we are tying a bow … Continue reading Mission Accomplished

Do you Technigrate?

According to my Humanities teacher husband, everything we do is technology. When I use sidewalk chalk in teaching Venn Diagrams or ropes to teach linear equations or even good old-fashioned pencil and paper in the teaching of math, I am integrating technology into my classroom. After all, cavemen didn’t have these tools. But I digress… According to Edutopia what we mean by integration of technology in the classroom is electronic media (computers, mobile devices, social media, and apps) which allow not just for greater understanding, but also for creation, communication, and connection.   “Take out your calculators”, “Google the formula for compound interest” … Continue reading Do you Technigrate?

Tell Me a Math Story

At first glance I wondered what the heck am I going to do with this? Digital storytelling in math?!? But I started thinking–it doesn’t have to be my OWN storytelling that I share. Have others shared math stories? Oh yeah, there are some good ones. As a high school math teacher, I’m really not interested in “every-day” math videos. Telling time, figuring out tips and sale prices, to be honest, that’s elementary math. The truth is, I don’t use most of the math I learned in high school, except, well, to teach math in high school. Does that mean I … Continue reading Tell Me a Math Story

The Koch Snowflake: Infinite Perimeter, Finite Area

Today my students are answering this question: Can a geometric figure with a limited area have an infinite perimeter? They are working with the Koch Snowflake, a simple example of a fractal. Fractals are objects whose essential form repeats itself with every iteration and when zooming in and zooming out. The Koch Snowflake starts with an equilateral triangle in Stage 1. Stage 2 divides each length into thirds and extends additional triangles from those sides, resulting in 12 distinct sides. In Stage 3, each length is again divided into thirds, resulting in 48 distinct sides.   This pattern continues infinitely with … Continue reading The Koch Snowflake: Infinite Perimeter, Finite Area

Nine Tech Tools for (Math) Teachers

“I can’t figure out this calculator!” She was staring at the screen, trying to change it from radians to degrees. It was a matter of pressing three keys: down, right, enter. I asked her how she figured Snapchat out and within two seconds her calculator was in degree mode. Just like that. Let’s face it. Technology is here to stay and kids are naturals at it. They’ve grown up with computers and smart phones, and have used technology seamlessly in their lives to hang out with friends, find information, listen to music, watch television and films, look up recipes, call grandma. It follows, then, … Continue reading Nine Tech Tools for (Math) Teachers
