This is a really small lesson on Polygons. I taught it as a half lesson. Includes a definition of a polygon variation theory thing.

Plus my first ever Quizlet! I liked doing this. I played it as a live game. You can see it in this little video.
Pupils are presented with a term and a definition across several screens, so they have to work together. I really enjoyed doing this.
It’s easy to fall into the trap of ‘I should do Quizlet all the time!’. I think it’s only really good for learning definitions, but it’s definitely a good tool in the arsenal.
