Northwestern Middle School Computer Labs - Math
The picture above shows the infinity and pi symbols.
I used contact paper for transfer tape. I cut contact paper (the type of you buy in the grocery store, KMart, Target, etc. to line your shelves. I like the clear contact paper so I can see exactly what I'm doing.) I rubbed them on tables a few times so they weren't "too" sticky. Then I would put the sticky side of the contact paper on the unsticky side of the vinyl (it was already weeded at that point). I found that if you made certain the corners were well stuck you could then pull the letters away from the backing of the vinyl. I would line the vinyl with the contact paper up in the correct place on the wall and rubbed it onto the walls. I would then carefully pull the contact paper away from the vinyl. It takes a good bit of work to burnish the letters down on cinder blocks. I would run my fingers along the edges of all the letters until they were firm. I also would pull the letters back up and push them into the cracks between the blocks. In the picture above, look at the T, O and W. Each of these were arranged in the crease so they would be firm against the wall. Most, but not all of the graphics were done without using transfer tape. This room required more transfer tape than the language arts lab. The math symbols had enough edges and the compass was especially difficult. Anytime a graphic had lots of edges I used transfer tape to give it a bit more substance and make certain it wouldn't stick to itself when I was putting it on the walls.
