A few years ago I started using visibly random groups & vertical non-permanent surfaces in my Math classroom. I got so excited about these strategies when some colleagues brought them back from a PD they had attended and immediately changed my classroom routines & setup. These strategies come out of a body of research by Peter Liljedahl on the Thinking Classroom.

Peter came to Ottawa last week for our Math PD day. He keynoted our event as well as offered workshops, both beginner & advanced, on how to apply his research findings in our classrooms. I tell everyone I can about how much Peter’s research has changed my classroom for the better, and so after his recent visit I decided to work on sketchnoting & sharing his research.

Here are my first two sketchnotes:

**Visibly random groupings:**

**Studenting behaviours around homework & studenting behaviours in the “now you try one” teaching model:**

Stay tuned for more sketchnotes about the Thinking Classroom!
