A few of my lesson plans went from sweet technology-based plans to me cutting, folding, and stapling booklets together (the original Power Point), but we've made it work! I had a teacher who said every day in the classroom is "an opportunity to practice flexibility." She was right.
This summer, I bought three large sheets of this dry-erase board material at Lowe's, and my dad was kind enough to cut them for me. He even rounded the corners to ensure we had no injured 5th graders :) Following suit, my mom had a ton of ugly-colored felt she wanted nothing to do with, so I cut it up, and it's made great reusable erasers for our boards. I store them in a milk-crate under one of our counters, and these are pulled multiple times a day. I snapped this picture Friday to send to my dad, to which he replied, "See! You don't need an IT guy for everything!" I love him.
These cost me $25 total (granted, I didn't buy felt), and each kiddo brought a dry-erase marker to school. There's no reason I should need to replace these soon, and they were so much cheaper than what you find in a teacher supply store. Lowe's would even cut them for me (I asked), but they only had was a hack saw, so I would've needed to sand edges...it can be done, but I had other options.
