From Betsy on Leesepea’s blog:

“Students turn in an assignment (say problems 1-20), and the teacher checks it. THERE IS NO GRADE. The teacher simply marks the paper and returns it to the student. The student then fills out a simple chart that is divided into three categories. At the top is “Problems I Got Right”- students simply list the numbers that they did correctly. Next section is “Problems I Got Wrong, but Know How to Fix”. This is self-assessment. The child has to go back over the problems and see if they can spot the mistake. The final section is “Problems I Got Wrong and Don’t Know Why”. These are the problems the students need help on. The focus is narrowed for both teacher and student, and a quick way to see if everyone is struggling with the same thing. It is also validation for the student- 9 times out of 10, the first two categories will have more numbers than the last one. And since there is no grade attached, it is non-threatening. My students love this.”
