• Transum,
•
• Solving problems like this has been an activity used for many years to introduce students to the methods used for solving simple linear equations. It is a good analogy for developing the notion of ‘doing the same to both sides’ to keep the equation balanced.
• Sycamore Class, Buckfastleigh Primary, Devon
•
• This challenge helped our class to use our brains first thing in the morning and we even managed to solve the problem. Year 5.
• Mrs Clay's Maths Set, St Helens ,, Pontefract
•
• We really enjoyed this starter. It was a good introduction to algebra.
•
• The graphics are (as usual) very high quality. It would be amazing to have an interactive version of this (showing one balance at a time) that pupils could select what to remove from each side, then click a button to see those items go, maintaining the balance (or tip, if they've got it wrong), leading them to a step by step approach to solving / showing working, rather than just 'here's the answer' approach. Would be a brilliant teaching aid!

[Transum: Good idea, I'll put it on the 'To do' list. Thanks]

## Numbers and the Making of Us

I initially heard this book described on the Grammar Girl podcast and immediately went to find out more about it. I now have it on my Christmas present wish list and am looking forward to receiving a copy (hint!).

"Caleb Everett provides a fascinating account of the development of human numeracy, from innate abilities to the complexities of agricultural and trading societies, all viewed against the general background of human cultural evolution. He successfully draws together insights from linguistics, cognitive psychology, anthropology, and archaeology in a way that is accessible to the general reader as well as to specialists." more...
