Reflection: Student Feedback Adding and Subtracting in Columns - Section 3: Closing


In the closing today I ask students to give me a thumbs up, down, or across to show how they are feeling about adding and subtracting using the base 10 house. I have watched students today and made notes on my clipboard about who was struggling, who seemed to want to skip this step altogether and just give the answer to the problem, and who seemed to understand the process. Now, as I look around the room at student opinion, I quickly match their feelings to what I am thinking. 

It is important to let students evaluate their own learning. It builds a sense of awareness about what they know, what they are in the process of learning and what seems impossible right now. We want to move students who know the process on to other things, work with the children learning the process to continue to build their confidence, and find alternative ways to support those who think it is impossible. According to Vygotsky, when children feel something is doable with help, they will work at it, but if they think it is unobtainable, they will just quit. I don't want anyone to give up, so I look at my struggling students, especially those who know they are struggling, and plan additional experiences with building numbers with base ten blocks and moving the blocks to count them so I can bring them out of the area of impossible.
