'This is a great little book for teachers based on robust evidence.' - Carl Hendrick, Head of Learning and Research at Wellington College *NOTE* If you're looking for ways to short-cut the amount of time you spend planning lessons, then this book is not for you. The approach outlined requires effort and practice, that given time, will lead to higher quality outcomes for less input. OVERVIEW This book is for any teacher who's interested in improving their lesson planning and practice. It outlines a set of mindsets and habits you can use to help you identify the most impactful parts of your teaching, and put them centre stage. It's about doing less to achieve more.
