Topics: Starter | Averages | Data Handling | Statistics

  • Mr Hand's Class Of Legends, The King's School Gloucester
  • Too easy!
  • Sam Woodward, England
  • Good and challenging at the same time.
  • Margaret, Lajamanu School NT Australia
  • Looks good, could engage students in finding mode. But what's a Smile test? Percentage of what?

    [Transum: The Smile Test was a made up term for the purposes of this starter.]
  • Hagelsteens, Netherlands
  • And what is now the answer ?
    There is no median?
    Usefull in lesson.

    [Transum: As there are an even number of faces the median will be the value mid way between the middle two faces.]
  • Sarah, NC
  • Love this, great interactive board activity.
  • Maria Darroch, Rolleston College
  • I really liked this starter, but there was nowhere to have their answers checked and because the numbers change when you click on it, I couldn't prepare in advance. But it gave us good discussion around the median.

Have you read Craig's book yet?

Craig Barton must surely be the voice of Mathematics teachers in the UK. His wonderful podcasts interviewing the industry experts have culminated in this wonderful book. As Craig says: "I genuinely believe I have never taught mathematics better, and my students have never learned more. I just wish I had known all of this twelve years ago..." more...

"How I wish I'd taught Maths" is an extraordinary and important book. Part guide to research, part memoir, part survival handbook, it’s a wonderfully accessible guide to the latest research on teaching mathematics, presented in a disarmingly honest and readable way. I know of no other book that presents as much usable research evidence on the dos and don’ts of mathematics teaching in such a clear and practical way. No matter how long you have been doing it, if you teach mathematics—from primary school to university—this book is for you." Dylan Wiliam, Emeritus Professor of Educational Assessment, UCL.

Casio Classwiz Calculator

There is currently a lot of talk about this new calculator being the best in its price range for use in the Maths classroom. The new ClassWiz features a high-resolution display making it easier to view numerical formulas and symbols but it isn't a graphical calculator as such (it has the capacity to draw graphs on your smart phone or tablet, via a scannable QR code and an app).

As well as basic spreadsheet mode and an equation solving feature you also get the ability to solve quadratic, cubic or quartic polynomial inequalities and the answer is given just as it should be written down, using the correct inequality symbols!

This calculator has a high-performance processor and twice the memory of previous models ensuring speedy operation and superior computational power.more...
