Since I had to teach remotely from both schools when the pandemic hit I needed a whiteboard! What a tremendous help and not expensive at all. I did not hang it permanently on the wall as I am using my dining room lol. It was the best investment to help in this pandemic. My students are finding it helpful as well.
Since I'm teaching from home this whiteboard is just a smaller version of the one in my classroom. It has enough space to write a simple equation and model how to solve it by drawing pictures. The only thing I wish it had was a stand so I could stand it up on a table. Right now I lean it against the wall because I don't want to hang it up.
I needed a large dry-erase board to virtually teach my 5th grade class. It wasn't too difficult for my husband and I to put up; however it would have been easier if there was a pattern to assist w/ placing the anchor screws -- we used a yard stick and level. I do recommend buying drywall anchors. and the top brackets were very difficult -- nigh impossible -- to tighten down. It was a necessary purchase a little more than I'd have like to have spent but... important.
