Here are a couple of things that I do in my classroom that help me.
If there is one thing that I use a lot in my room it is page protectors! It is probably not much of a tip because I am sure that everyone already uses them but I use to think that I had to laminate everything until a colleague handed me page protectors and I was hooked. I use them for all of my math mats, playdough mats or anything that I need to be protected from those little hands. I even hang them on my PDSA wall to slide in my new goal each cycle. Many of my math mats require the students to write an answer so the page protectors are perfect because the students can use white board markers to write on them and it wipes right off. They are great!
