I have been a teacher for over 20 years - all the stuff I upload has been tried and tested in my classroom. I don't mind a discussion on Twitter too where I also share new resources. I now have a personal website: https://andylutwyche.com/
This is just a lesson on scatter graphs that I wanted so that I could just hand out one booklet and then teach the class without the faff of them drawing axes etc. It goes from simple plotting to describing correlation to using a 'line of best fit'. Two sets of questions depending on which Key Stage you are teaching.
