Reflection: Rounding Numbers to ANY Place - Section 3: Concept Development


agggghhhhhhhhh --- That's me whisper screaming from my desk right now. As you can tell in my video, this was a challenging day. I sat down and went through my first group of students' exit tickets.  It was worse than I though.  Rounding to any place really threw a kink into my student's thinking.  Students who were doing great with rounding to the nearest thousand even got that wrong on their exit tickets.  Some students did fine, but I'm perplexed about the students that then got it wrong.  These students are weak in conceptual understanding, I know that, but we had such a positive day Friday, it was hard seeing those exit slips today with so many incorrect. Tomorrows lesson is entitled rounding in real life, and I'm thinking some of this may make more sense to students when the numbers are within a context.
