Hi Room 5,
Damien you did a great job of your model of our classroom and got most of it right. We want to help you all out a wee bit as we have learned that it is very hard to communicate in writing exactly what our classroom looks like.
We are not sure if Mr Webb wants you to see a visual model of our classroom or would prefer just a written description so we'll leave it up to him whether he shows you this or not. We wanted to take a photo or video of our classroom but Mrs C-M thought that might ruin the fun for you.
So here's a video of a model like Damien's. We haven't put the windows/ whiteboard/ projector in but if you reread our comments you might be able to work it out.
Good luck. We can't want to see your minecraft creations!
