Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 19 June 'Starter of the Day' page by Nikki Jordan, Braunton School, Devon: "Excellent. Thank you very much for a fabulous set of starters.

"I am thinking that for the deconstructing graphs activity an additional feature could be to require students to write the equation of the line before receiving the trophy. An additional feature could be to require students to label x and y axis and write a context(story) for the equation. This would require deeper thinking and learning to take place."
