## Reflections on a Day

It’s been almost three months since I’ve written here – so long that I almost forgot this blog was a tool I could use in my teaching. For the first time in a while, I feel like I just have to write about the day I had yesterday. All three classes I teach were remarkable […]

## Excel Explorations

This is not the first year that I have used Excel as a teaching tool, but I have been more purposeful about it than in the past. Today we began our fourth “Excel Exploration” of the semester in my #TrendingNow class, and I feel like it’s paying off as everything comes together. Here are the […]

## Formative Per Day #1

Today was the first day of regular classes with the 11th and 12th grades at VPA.
