More work with my Autistic student. She was happy to report her school work with fractions was "too easy."

I treat her pretty much like any other kid and use the same basic lessons to provide powerful understanding of math concepts. After the concepts sink in math itself is pretty easy.

It was late when I made this screencast and my verbalization of the story problem in the middle is quite screwed up, lol!! One day will learn how to edit. I left it instead of re-cutting it because even with the verbal errors I think the concept comes through at last, and you can see even if you make a mistake you can still do a lesson. So many parents and teachers never get started for fear of "doing it wrong", some of you may have even gotten it better due to my errors because you thought to yourself "what he's trying to say is..." Anyhow here it is correctly:

If each student got one bottle of water we could give 120 students one bottle each.

If each student got 2 bottles each we could give 60 students 2 bottles each.

If each student got 3 bottles only 40 students would get water, if we gave each student 4 then we could only give 30 students water...when I was doing it with her I was saying correctly and she understood what I meant. In the picture we see 120 broken into 4 groups of 30 each...we could also form a rectangle and count the sides.

Here is a good reason to use rectangles instead of circles or pies when presenting fraction concepts. being able to draw it demonstrates comprehension and moves the student from the concrete to pictures to symbols naturally. For more on what that picture represents and how we develop the concept of equivalent fractions go here.
