((((Valed)))) xxxx

Don't usually do the silly hug thing- but they are brackets after all!

2. mmmmmathsNew commenter

Love it....and I was going to suggest circle theorems as my second request!

4. Colleen_YoungOccasional commenter

Fantastic - checking it now.

5. emilyisobel

Valed, that is brilliant. I really hope that I have a data projector next year so that I can use it!

6. Colleen_YoungOccasional commenter

This is great Valed - all very clear and I can't see any errors.

Two tiny things I would change..

the wording in the same segment example
'the exam tries to confuse you'.
As an examiner I keep telling them how fair it all is so don't want them to think the examiners are out there to trick them! So, you are quite right to point out that the diagrams can be confusing, but I would just say just that, ie watch out for confusing diagrams!

Two tangents from a point outside circle:
I think I would change the wording of
'tangents are equal' to something like 'the tangents are equal in length'

Thank you so much for doing this. I shall in fact use it Tuesday!

7. Colleen_YoungOccasional commenter

Forgot to say - I would add the solutions to the examples. I often do this with my flipcharts or PowerPoints - create a duplicate slide with the answers so once they have tried the example, the correct solution can be shown.

8. valed

OK Casy - I have made the two textual [is that a word?] changes suggested.

Have not added the solutions though to the questions pages - personally, I use these pages to scrawl all over on the IWB.

What I would do is print off Handouts of the questions for pupils to use, annotate and stick in text books - best of both worlds!!

Of course, please feel free to change it if you wish.

Thanks for the topic - that's one less to write for next year.

Now, what next ???

9. Colleen_YoungOccasional commenter

Brilliant. Thank you again.

I like your idea of the handouts.

You have other PowerPoints on Tandy's site don't you?

Are you trying to build up the complete GCSE course?

10. mmmmmathsNew commenter

Maybe too much chocolate but I'm having problems with the pp. If I try to start at any of the first 5 slides it jumps to slide 6 'a typical example'.

11. Colleen_YoungOccasional commenter

choose set up show change from 6 to 1

12. briceanusNew commenter

Valed, excellent presentation, I am picky though. Near the start you say we will look at 4 and do some examples. You actually introduce 6 (I think!!), maybe you got carried away, or initially didn't think you'd do so many.
How about one on creating box-plots from cumulative frequency graphs if your looking for more ideas.

13. valed

BRICEANUS

Well, yes - I did 4 in first section [if you include the special case, angle in semicircle], then went on to cover the tangent in second part.

As for CF & Box Plots , your wish is my command here http://www.btinternet.com/~mathsanswers/html/resources.html

Can't say I just wrote this - I did it some time ago.

NEXT PLEASE!!! I'm on a roll

14. Colleen_YoungOccasional commenter

Vectors?

Loci?

Constructions?

These all strike me as topics not well covered elsewhere.

15. emilyisobel

Er, how about proof - something that there are few good resources for.

*ducks and runs for cover*

16. mmmmmathsNew commenter

PP working fine now thanks-learn something new every day!

I'd love one on proper use of geometric notation which would then lead onto geometric proof!!!!!!!!!!!

Any chance?

17. valed

OK

1 Casy

I quite fancy tackling Vectors! That will be next. I can assume we're talking Higher GCSE?

Have you noticed I like messing around with lines / arrows flying in?

2 emilyisobel, duck

I'm happy to try Proof : can you at least give me a hint as to the sequence in which you want this addressed. ie prove what, in which order etc As ONE ppt or separate?

18. Colleen_YoungOccasional commenter

Arrows flying in - I can't wait!

Higher GCSE - yes indeed.

Now let me see - I need that done by....

The post you are referring to could indeed be taken as provocative, any poster posting such a message should not be surprised by tongue in cheek replies!

Hi Valed,

Could you write one for circles interesting with straight lines - its one of a few that I can't find on the internet.

Cheers
David

Intersecting, perhaps?

Can you give more to go on? Is this in connection with trig or something else?
