The Great Elf Game is a fantastic Christmas resource which comes from http://www.teachmathematics.net. I have created a walkthrough that takes the class through each day of the game. I have also simplified the spreadsheet used to score which I have printed out on A3 for the teams. Enjoy!
These are stuck on each table in my classroom. They help my students to construct meaningful sentences around the 'What went well&' and &';Even better if' headings.
This is a two page version of the A Level Maths formulae book for Edexcel.
