Reflection: Checks for Understanding Rounding to Check Addition - Section 3: Student Practice


During the student practice time, I was continually checking for student understanding. The majority of students were able to successfully meet today's goal. Here is a Proficient Student Sample. I loved how neatly this student lined up digits when adding multiple addends on the last couple of problems. 

Also, this conversation alone was so wonderful to witness: Estimating 52098 + 6048. More importantly than successfully completing the task is knowing how the strategy will be useful in the future!
