Reflection: Intervention and Extension Combinations, Day 1 - Section 3: Center Time


I wanted to reflect on two things during my observations and student interactions during the 1st Center Time activity.  

I have one student who has a difficult time organizing her work and being able to record her thinking. I wanted to be able to work with her and model appropriate ways of recording her work.  Watch the video entitled Differentiating for Hannah to hear what I did.  Also, you can look at the image of her work.  This too is found in the section resource (Hannah's Work).

The second video is the use of a observation sheet/checklist that I used as I was circulating.  Watch the video (Reflection on Checklist) and look at the image of the Completed Observation Sheet.
