Reflection: Student Self-Assessment Addition and Subtraction Expressions - Section 4: Closure


In the video, when my student said that "my answers are right," I felt very proud.  I always encourage my students to be confident and know what they are talking about.  Sometimes, when I question my students, its just to see if they will stand firm on their answer or change it.  I tell them that you must always know that your answer is correct.  If you have done the math, then stand on your answer.  This student exhibited this stance.
