New Beginnings

I’ve been trying to capture for myself some of this whirlwind as it rushes by.  I can’t help but compare what happened today with what has happened most other “first days” of school.  As I’ve mentioned before I work at an awesome new school called the Riverpoint Academy and we just completed our first day.  I had […]

Radical Collaboration

Glenn Williams and I are team teaching this year. But it’s likely not what you are thinking. I’ve team taught before, but not like this. This isn’t like anything I’ve ever thought to think of before and I’m guessing that this kind of collaboration is unknown to most all of you who have spent your […]

GeoGebra and Desmos

GeoGebra is an amazing piece of free software for visualizing and demonstrating math concepts.  It is an awesome tool for creating dynamic constructions but we won’t be focusing on that today.  Instead we will be using GeoGebra as a function grapher with great flexibility to adjust window settings and change graphs dynamically using “sliders.”  More about […]

Convincing Data

We are still in the “Data Analysis” unit in our Algebra 1 class and we are all set to talk about Correlation and Causality.  I’ve got some great worksheets (yes, such a thing exists) but my ongoing concern is that I miss the opportunity for students to see math as meaningful. I really want to […]

A matter of data

I’m teaching an algebra unit called “Analyzing Data.”  We’re doing basic stuff really and each year in the past its gone pretty well.  But I’m not too great at doing the same thing each year. I tend to get bored once I feel like I’ve found one particular solution to a given problem. So this […]

More GeoGebra Goodness

My students are using GeoGebra again today and yes, it is still just as amazing as I previously thought.  Today both my Pre-Calculus and Calculus classes are using it.  The Pre-Calculus activity was awesome and it generated lots of discussion and exploration today. Before I tell you about it though, I think you should watch […]

Revisiting my commitment

Last year I re-established my commitment to use technology that was meaningful for learning.  I have spent most of today working on building various presentations and generally geeking-out with the tools. I have re-discovered some pitfalls that have caught me in the past.  First, it is so very tempting to sit down with a new […]
