  • Hello, this was easy peasy but we enjoyed it, particularly Tamera who says she has a room at home shaped like that.
    We love a good starter, especially on a Monday morning. x
  • Lewis Paton, Carnoustie High School.

  • It was shapetastic.
  • 7abM3 Maths Class, King Alfred's College OXON
  •  
  • Today's starter sparked off a good chat about shapes. Eventually most of my class could see how to get the answer.
  • Transum,

  • So when the answer is realised there is typically a sense of amazement that the calculation is so simple. As a follow-on activity pupils might be challenged to draw another seemingly complex shape that has a simple calculation to calculate the perimeter. This is a useful activity which helps provide a sound background for geometrical problem solving in general.

  • My year 6 class just loved this puzzle.
  • Mrs Walker, St.James' School

  •  
  • My class found this problem angleastic!!!!!

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...
