  • My year 8 enjoyed this as a starter. I added some much bigger totals such as 140556.
  • Transum,

  • This is a classic trial and improvement starter in which pupils can try guessed solutions and, if they don't give the required result, try a modified guess which will take them on the route of homing in on the correct answer. Being a little more sophisticated pupils might realise that the middle number will be close to the cube root of the given value. Some will be able to use their calculators to find a cube root while many other will not know how to do this. See the bottom of the August 12th Starter page for a basic method for finding the cube root of a number.

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...
