  • These are good fun - more please
  • Sara, Bradford

  • I think this kind of activity is bad - it encourages kids to think of a letter as standing for a thing instead of a number which damages their developemnt of understanding algebra. For example 7d in a w is 7 days in a week in your puzzle but algebraically to change weeks to days we do d=7w or "to find the number of days you multiply the number of weeks by 7" because in algebra we use the w to mean the number of weeks not one week - I think it deepens misunderstandings.

  • We think these type of maths starters are very thought provoking and make your mind get on track.
    We think Sara from Bradford is wrong about saying that the algebra can be misunderstood, it's only in fun.
  • 10 Ma2b, Ilfracombe Arts College

  • We agree with Year 10 in Coln and think Sara needs to lighten up a bit.
  • Jenny, St Clement Of Rome

  • 1000M in a K.
  • Tamia Nero, Berrywood Primary School In Hedge End

  • I think this starter of the day was very easy but I still had fun doing it.
  • Rob, Leicester

  • Sara can't cope with the date either, as it's meant for the 30th. I'd say she could do with some more math's lessons. Also, just don't do it, why write a comment?
    I like these. Took me a while to get the 3 f in a y, there's always one.

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...
