I'm excited to be linking up with Holly at Fourth Grade Flippers. My Tried It Tuesday is dry erase sleeves From Oriental Trade.
I use these daily in my classroom. They are great for center games and any repetitive skills you want to practice. I got a sample of one at a teachers conference. It had an opening in the side, and I fell in love with it. However, they are really expensive. I recommend trying these first. If you already use whiteboards in your classroom, I'm sure you will love these, too. You can get a dozen for about $12 at Oriental Trade.
