You can buy washable chalk pens from most stationary shops for about £3. Underneath is a picture of my windows at the moment with some work on representing data in bar charts and pictograms. Also I have a quick plenary window for ‘one thing I have learnt’ and ‘one question I still have’ post its.
Students LOVE writing on the windows with the pens so I often use this as a prize for them winning bingo or other little activities. I will let pupils write a fact they have learnt or a little example on the window. The possibilities are endless… try it and your windows will never be clean again!
