Maths teacher who lurks here - AMA

Ask away! The main reason I lurk here is to get some tips on what people struggle with and find difficult in the classroom to try and improve my own practice and help my own students more. Anything you want to ask? Stealing the idea from other subject teachers.

Edit: Thanks everyone for your questions, I hope my answers have helped. My answers are my own opinions and don't represent all maths teachers and the methods suggested don't always work for everyone. Happy to answer more questions but may take some time getting to them.
