I have never tried math centers before in this way. I was wondering how you can be sure that students are practicing the concepts and skills accurately. For example, if students are building numbers using base 10 blocks and then cleaning them up, and I never see their work, then how will I know that they are not practicing incorrectly the whole time? I know that during individual conferences and small groups I will be working closely with them, but I feel like it could be detrimental to a student to practice a math skill or strategy incorrectly until I "catch" this problem.
Thanks!
