I previously blogged about why I like getting students to compare how tricky they might find two similar-looking Qs (bossmaths.com/which-is-eas...) Here's a new pair that I hope might generate an "aha" moment for students.

Had a great discussion in our department CPD about the link between student oracy, mathematical communication and understanding. How do you ensure students know which expression you mean when you are explaining? How do you explicitly teach them to talk about their maths? #MathsToday #iteachmaths

Ages ago I used this (non-calc) Q with my KS3 & KS4 groups. None saw the answer immediately; they all tried finding Alice’s and Bob’s numbers en route to answering the Q. Used it again with selective school-bound primary Ss. Surprised none saw the answer straight away either #edusky #Mathstoday

I'm a bit obsessed with old textbooks for children in mathematics. Particularly from the 50s/60s both from a graphic design perspective (some are so pretty!) and a content perspective.
