  • Kerry Grindle, Litherland High School

  • On the Starter of the Day for October 13th, if you follow the flow chart exactly then the number 1 should never have been written down at the end.
  • Graham Ingram, Furness School

  • Excellent 10 GI love it
  • Mr Fawer, Class 6
  •  
  • My class loved it.
  • Borris, Ilkeston
  •  
  • The lowest power of 2 that is also bigger than 5 is 8, which is the answer.
  • Mr M's Year 8s, Canggu Community School

  • This gave Aria a headache, but everyone else loved it! Thanks :).
  • Year 6, Bryanston Square CE
  •  
  • We struggled with this and failed to understand how so many numbers were generated. Is this higher level maths?
  • David, Illinois
  •  
  • The end of the flowchart should go to the second bubble, "write it down," not the first.
    This is an employment of the Collatz Conjecture http://en.wikipedia.org/wiki/Collatz_conjecture, basically, any number (save for a few) should eventually end at 1.

    [Transum: Thanks David for sharing the link to the Collatz Conjecture information. Regarding the flow chart, it is meant to show returning to the second bubble.]
  • Class 5, Lady Royd PS
  •  
  • We found it easy and loved it.
  • XD,
  •  
  • You should have never have said over 5. You should have said 5 to a limit because kids start choosing numbers like 1,000,000 and then it's too hard so they give up.

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...
