I visited a year one class at Windley School and saw an amazing Discovery Time with a focus on photography. It had began with the teacher taking photos of each student and then progressed into:
making their own cameras
constructing photo frames
setting up a photo shop
There were of course other DT activities going on at the same time but these three activities provided a focus.
The photo frames - made out of driftwood involved some good carpentry skills and the children soon discovered that some pieces were softer than others - lots of great vocabulary extension work going on around the table.
These activities continued over several Friday sessions. They were hugely successful, yet quite simple to organise.
