Don't usually do the silly hug thing- but they are brackets after all!
Love it....and I was going to suggest circle theorems as my second request!
Thanks....(have already added your site to my favourites)
I'm sorry but Circle Theorems ppt is finished!
Will you run it and check out the content and sequencing for me - just to make sure there are no errors.
Fantastic - checking it now.
Valed, that is brilliant. I really hope that I have a data projector next year so that I can use it!
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!
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.
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 ???
Brilliant. Thank you again.
I may well tinker..links to Sketchpad for example.
I like your idea of the handouts.
You have other PowerPoints on Tandy's site don't you?
What have you already done?
Are you trying to build up the complete GCSE course?
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'.
go to the slide show menu
choose set up show change from 6 to 1
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.
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
These all strike me as topics not well covered elsewhere.
Er, how about proof - something that there are few good resources for.
*ducks and runs for cover*
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!!!!!!!!!!!
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?
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!
Could you write one for circles interesting with straight lines - its one of a few that I can't find on the internet.
Can you give more to go on? Is this in connection with trig or something else?
