If you have any.
We've had our whiteboards removed. And they've been replaced by very bright and clear TV screens and apple TVs that are also connected to our class PCs.
BUT.... I am missing being able to write directly on the screen neatly and to annotate work that my PC is displaying.
The ipads have all the right apps, but I can't write neatly on them as I need ot rest my hand on the screen to steady my hand for neat writing, and then it registers that touch instead of the stylus and I can't write.
I'm debating a digital slate thing, but don't know if they are the answer - or where to find one at a reasonable price.
