ELL and Math resources

Here's a really neat Powerpoint  resource I came across recently that looks at teaching math to English learners from a different perspective; that of the TESL person as opposed that of me, the math person. 

There is an absolute wealth of information in this presentation especially the linguistic identification of the different types of words used in math.

And here is another really good account from the Virginia Department of Education that also gives some historical background to the theories involved in teaching math to English learners.

Finally here's a book that I probably should have read some time ago but have only just discovered.
It is the CALLA handbook. The book describes the development and implementation of the Cognitive Academic Language Learning Approach to teaching English learners.
