My new book “Yes, but why? Teaching for understanding in mathematics” is now available for preorder from most retailers.

The book is designed to explain why things work in mathematics, such as formulae, algorithms and general patterns and rules.

Enjoy reading your book – lots of great ideas. Helps me have a fuller understanding. Just a quick query – on page 58 bottom section, my calculations suggest the answers should have one more place value and a zero before the final digit, eg. 123456789 x 9 = 1111111101. Can you please explain?

Thanks for the comment. They should read 12345679 (no 8). I have let the publisher know. Many thanks.

Can you email me your address (e.southall@hud.ac.uk) I’d like to send you a signed copy of the next print run as a thank you for pointing this out 🙂
