    What about matricies and transformation?

    As in "Which matrix transforms shape A to shape B"

    My students find it one of the hardest topics at IGCSE.

    I teach the unit vector method and also the generalised method of letting the required matrix be ABCD and multiplying the original matrix and forming 2 sets of sym equations.

    Some of my student just memorise the list of mattrices and the functions.

    Just had a thought,is this in GCSE?

    If not, just ignore me.
  6. How about volume of a pyramid? Trying to explain where the formula comes from is always tricky! I think you would definitely get a gold medal if you succeeded with that one! And thanks for making your materials available, some real gems there.
  7. I can do that! [​IMG]
    Gimme a few days
    Ta muchly

  8. That's fabulous, look forward to seeing the results!
  9. That's totally mint! Sorry for lapsing into teen speak but that's brilliant. I saw a pretty complicated example on NRICH with three pyramids fitting together but I think your six is much more intuitive, I like it a lot.

    If it's not a trade secret, what are you using to draw your diagrams with? The one with the pyramid inside the cube looks particularly good.

    Many thanks again, I only made the suggestion half jokingly but this will be really useful.
  10. Thanks but I am such a NORB!!!!! [​IMG]
    There is already a MUCH better version of this already on MathsAnswers - the second last on the Shape menu.
    I really must check next time!!! How embarrassing [​IMG]

    But, I was bored....
    .... and still am, actually .........
  11. I hadn't heard of a NORB before so I googled it.

    "NO Reason Boner
    Popular among thirteen year old boys.I got a NORB during gym class and had to goto the nurse for her to rub ointment on it."ps. I had forgotten that sort of proof for the pyramid. Thanks for the reminder.
  12. Oops! [​IMG]
    Where I come from, NORB means a fool as in Nought-but-a-fool....
    ... you had to be there!
    Apologies for any offence....

    valed - just checking Algebra. Formulae - changing the subject- is that anywhere?
  14. You need one?
    Unknown appearing once or twice or both?
  15. Feeling a bit of a NORB myself: Valed's definition, would definitely be worried if it was Mathsteacher1963's definition;) I'd only raided Maths Answers a couple of days ago and forgot to spot the pyramid volume presentation.

    Congratulations on the retirement, everyone who I know who has retired from teaching looks so relaxed!

    valed both please - my Year 10s need this!
  17. Any particular rush or can you defer it a week or so?
    As it happens, I need to teach my year 9's this after half-term so this is my next project.
    PPT will be in 3 parts: 1 = Subj once 2 = Subj twice 3 = New subj raised to a power
    I'll do examples of each type, step by step. I will not be reviewing factorisation, multiplying single term over bracket ...

    Sounds brilliant valed.
  19. Change Subject of Formula is now available here
    Bit rough - comments / feedback please.
    Ta Val
  20. New Powerpoint on LINEAR INEQUALITIES here

    I would really appreciate any feedback on this and the 'Change Subject of Formula' one recently.
