I know you can use showerboard/tileboard to make a dry erase board. However, I'm trying to do something a little bit different. I want to use one of my bulletin boards to make a Calendar Math board that covers several concepts quickly. I wanted to be able to attach smaller sheets of dry erase material to solve problems on there. I've tried laminated posterboard, but the dry erase markers do no come off it very well, which means a lot of daily cleaning for me. I'm not sure if the bulletin board would hold several pieces of smaller tileboard nailed into it. Are there any other materials I could use that work well with dry erase markers?
