Getting the right answers in math is only half the problem. Understanding why what you’re doing works is the part that often stumps students and teachers alike. Does math feels like a collection of random rules and steps that somehow lead you to an answer? Don’t worry, you’re not alone.
Ask why do we have odd and even numbers? Why do two negative numbers multiply to make a positive? Why do fraction operations work? What is cosine and where does it come from? Yes, but why? answers all of your questions, and sheds light on the hidden connections between everything in mathematics at school. Math makes sense. It always has, but until now maybe no-one ever showed you.
A must-read for those training to teach primary or secondary mathematics via university-based (PGCE, BEd, BA w/QTS) or school-based (School Direct, SCITT, Teach First) routes and current teachers wishing to deepen their mathematical understanding.
Look, the number of stars is going to depend on who you are and what you do. Are you someone starting out in a career teaching math? Stop reading this review and go buy a copy. Have you been teaching math for some time? Probably worth giving this a read to either pick up some ideas for class or feel like you're getting a pat on the back for choosing to emphasize something other than rote memorization in your classes. Not a teacher? If math felt excessively dry and unconnected when you were a student, go have a read.
Very interesting book on teaching maths in a way that explains why. Accessible, could be used both by mathematicians and non-mathematicians, and relevant for teaching all ages and stages.
This a book I am happy to have and use to deepen my understanding of math concepts for teaching but also to have as a reference for topics I need a refresher on.
