Belle Cottingham

Belle is passionate about teaching Mathematics and finding new ways to engage the minds of learners on the subject. She has experience in writing textbooks and workbooks for Primary and Secondary Mathematics, and has worked with many publishers including Rising Stars, Pearson, Harper and Collins, Cambridge Mathematics, Schofield and Sims and Macmillan.

"All the problems and puzzles in the book are based on the everyday life of my own children and their friends, as well as other children that I have been lucky enough to teach in the past. I wanted to create books that are colourful, full of life and energy, because to me that’s what Mathematics is."
