So we all have Interactive White Boards now (IWBs) but at my school we are all using PWBs – Personal White Boards that is. Small whiteboards are part of many sessions, especially English and Mathematics. You can buy them in bulk from educational suppliers, or cheaply at dollar shops and department stores like Kmart.
My students, even though they are 11-12 year olds love using them, they are more keen to write on these than in their books (a pro and a con!). A quick glance around the room at what is on the whiteboards is a great assessment tool, and errors can be fixed easily without wrecking a page or paragraph in a book.
The cons are the constant buying of whiteboard pens, and of course training the students not to draw on them at the wrong time.
