If picture is worth a thousand words, imagine the power of three pictures at a time. Which is exactly what former graphic designer turned teacher and leadership team member Ben Keeling has done.

First spotted by Independent Thinking founder Ian Gilbert following a Twitter exchange that stretched between Chile, the UK and Indonesia, this ground-breaking book uses three simple 'doodles' per page, each on a separate sticky note, to highlight key issues. Simple yet contagious, this book rewrites the rules when it comes to the literature of school improvement and should be on the desk of every school leader and teacher.
