Reflection: Developing a Conceptual Understanding Counting By 2s - Section 3: How Many Eyes?

 

Before reading through this section, it would be helpful for you to watch this video: A Teachable Moment.

As you can see this student had an appropriate approach of drawing a picture. What she is missing is the understanding of the 2:1 relationship and wasn't clear that there were 7 students not 7 eyes. The video is a great example of why you need to touch base with each student (as they work) and make sure that they are truly understanding what is being asked of them.
