Thank you GSC for so warm presentation of my PPT presentation! :-)

When we publish something on Internet, then it is not secret and I think anyone can give this link to anyone. So, all you can do it with my link.

You can see the presentation at
http://public.carnet.hr/~ahorvate/materials-English/Fractions/Fractions-revision.zip

(If this link will be broken, copy paste it into adress line of your Internet browser.)

So, I made PPT presentation for revising fractions.
I tried to put many different kinds of tasks into this presentation, so it is very long. Also, I tried to explain the same things in several different ways and to show that all of them give the same results.

Lenght of the presentation shows that there are so many things about fractions which must be explained carefully. So, it is not strange if many kids have problems with understanding fractions, especcially if their teachers don't explain many detailes.
And I saw several textbooks in which are skipped some basics (nor only about fractions, but in general).


I use this presentation in 6th grade, after finishing unit about fraction, and later when we want revise it.
I want to emphasize - this PPT is not good for introducing fractions! When kids learn it (and when they see some types of tasks first time), then we should give more examples for the same/similar procedures, facts etc., we should do it slowlier...
Also, then it would be good to explain the same thing in more ways, as I tried to do in this PPT.



Also, this presentation shows that computer (and projector) can be great tool which can help us to show some visual explanations in very easy and nice way, which could'n be reach without it.


Finally,
I want to emphasize that I also have several GSP files for
introducing many facts about fractions. I use them with projector and you can find it on
http://public.carnet.hr/~ahorvate/materials-English.htm
.

Before I had projector, I was't able to explain that things in so clear, nice and quick way!
So, I'm advising warmly to those of you who teach fractions, to take a look at these materials and to think about using them (or something similar) in your teaching.

I most kindly thank GS Chandy and Rex Boggs for support, great suggestions and help with the translation of presentation Fractions-revision into English !

Best wishes,
Antonija Horvatek
