A cut out clock face with hands. You will need thin card, glue sticks, and paper fasteners.
These can be used as individual clocks for pupils to learn to tell the time.
Then when the lesson is done, pupils can set the time and write it in the box provided.
Then the whole class can display their work and you will have a useful display/resource available to you from then on.
So fun lesson or two ... and an interactive display to freshen your walls, before the headteacher starts mooching around and tutting, all in one go ... bargain.
