Last May I posted about how I presented photos from the city to have fourth graders talk to me (and, more importantly, to each other) about parallel, perpendicular, and intersecting line segments. The photos I took I included in this post:
On a follow-up visit to that 4th grade classroom, I took some photos in their classroom. At first I just wandered around taking a photo of this and that but soon different students caught on to what I was doing and suggested things I should photograph. The most fun was when the “climate control” young man turned his back to me indicating I should photograph his shirt! He was usually focused on the discipline issues of one student assigned to him but that day they both found themselves engaged in mathematical thinking!
