Advice for teachers of mathematics.

The article presents some guidelines on how mathematics teachers can teach mathematics more effectively by using the new interactive whiteboard software. The interactive whiteboard can be used to write, rub things out, go back (and forward) a step, move and change the size of objects and delete things.
