Making moving toys for Christmas presents

During the last few weeks of the Autumn term, 5W made moving toys. We experimented with the use of CAMs and designed a toy for a Christmas present. Firstly, we made a practice model using paper and card so we could see how our toy was to fit together and move. When we were satisfied with our model, we used wooden CAMs and boxes to make our toy. It was a difficult task to ensure our toys moved smoothly on the CAMs.
