When you establish a safe and meaningful learning environment for your learners, the better learning experience they will gain. I've implemented self & teacher rubrics for my learners during centers for several reasons, I want my learners to go back to WHY they are here in the first place: TO LEARN. I began to get frustrated after putting together centers and some learners just wouldn't do the work. The parents would ask why he/she had a score or why a page was blank. Now with the rubrics, the parents and students can see just WHY centers are so important.
In order for them to have the optimal learning experience they must be aware of the several components of their math and reading brain. I want my learners to be at a moderate noise level to void cognitive overload, I want my learners to engage in "math" talk with stems like "Hey teammate, what strategy did you use for this problem?" vs. "What is your answer?", and I want my learners to help their brain stay on task no matter what!
To build center time that is meaningful & useful I have implemented (and still am half way through the year) a component of MATH workshop to my students slowly. We practice for weeks focusing on the new MATH center component before bringing in another.
I pass the rubrics out before centers begin (usually while my students are working on the warm up problem before centers begin). From the start they know they will be held accountable for their volume, use of tools, body movement, and so on. At the end of the centers (however amount I get in that day) students reflect & score. At the end of class I collect and quickly circle what I feel they earned. Slowly over time I stop giving the rubrics once they have mastered that component.
NOTE: Obviously, we as teachers do not have time to assess every single student for every single area every single center day. So I eventually only give the rubrics to those who tend to be inconsistent with their scores and need the accountability. I also sometimes give a graded rubric to those who WOWed me with all 4s. So keep that in mind. :)
