This week I finally listened to a podcast I have been meaning to for a considerable time – Craig Barton’s podcast of his discussion with Anne Watson and John Mason.
As you can see from Craig’s notes the discussion is wide-ranging; so well worth a listen, this will leave you with plenty to think about.
I was particularly struck by Anne and John’s Big 3 (or Big 5!) (scroll down Craig’s notes). The only website they mentioned is Underground Maths; a personal favourite – Underground Maths pages here). John Holt’s How Children Learn was my first reading on my teacher training course decades ago – still a classic.
This morning, I have been distracted from writing watching Anne and John’s recommendation – Polya’s video “Let us teach guessing”. (Also on YouTube). To hear the man himself talking to his class is a joy. Not a traditional lecture – join in with his class as they guess!
Much food for thought – you can hear Polya’s summary of what is important in reasonable guessing at 54:16. Including the all-important reminder that we must test our guesses.

From the University of California, Berkeley see this summary of Polya’s problem-solving techniques – including a summary, in the Polya’s own words, on strategies for attacking problems in mathematics class from the book, How To Solve It, by George Polya, 2nd ed., Princeton University Press, 1957, ISBN 0-691-08097-6.
For a useful document on cutting space with planes, the problem discussed in Polya’s class, see this University of Toronto resource.
You need to get hold of “Induction and Analogy in Mathematics” by Polya. Worth it!
