Escape Room Extension

For this term in extension we have been doing escape rooms. I was in a group with Angelica,Aye and Finau. We got to come up with our own theme and puzzles. Our theme was based on the horror movie smile. We planned on doing a physical escape room. Today we started on cutting the keys out for one of the puzzles. Our next step is to finish off the keys and start putting things together. 

Riveting Revision – Maths

This week we have a maths test, so we were tasked to look through this revision doc. There was work from all the things we have learnt this year.
