  • Bernadette Summers,

  • I like this and so did my pupils, extremely good idea.
  • The Best Maths Class Ever 7cd/M2, King Alfred's College, Oxfordshire

  • Too simple. Just 24 multiplication questions that everyone could do upsidedown... No offence intended cos we love your website really.
  • Murran, Oxfordshire

    Too simple!

  • We liked this: it wasn't too hard.
  • Beth, NB

  • Excellent warm-up when you don't allow paper. How far can they go mentally...that's how I used it.

  • It was a good warm up to get the class ready for harder times tables.
  • Transum,

For some it will be quite a challenge but more able pupils could treat it as a gentle warm up before the main part of the lesson begins. There is nothing wrong with a gentle warm up, athletes do it often. It does not create stress but allows the individual to enter the right frame of mind for the delights of the lesson to come.

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...
