In this workshop we looked at the following ideas:

1. We started with a visual proof of Pythagoras, using pieces of wood cut using a laser cutter.  We discussed using geometric ideas instead of algebra to solve a problem. 
2. Following this, we investigated a lesson I had created on group theory and symmetry using some more wooden pieces.    
3. Time was short, so we briefly had a look at symmetry in platonic solids using a gobstopper and some 3D kaleidoscopes that I made. 
4. We also made a dodecahedron using molecular modelling straws.  
5. Steve then showed us a great idea for making folding revision notes.   

I gave everyone a piece of mirrored acrylic - we are going to have a go at making a 3D kaleidoscope for homework and bring it to the next session!  
We all agreed to meet again in June after the exams - if you would like to come please let me know.
