straightace.com also helps with differentiated math. I have not tempted myself to look at that this year. I am eager to see how that works for next year. Right now the Front Row meets the needs of my learners and I want to stick to that.
readtheory.org 2nd (Advanced Learners) - High School
At readtheory.org, I created a class and I conferenced with each student regarding the reading level that they will be reading in to start off on. The students receive both non-fiction and fiction text with a small handful of of questions to go with it. When students are successful in that level, they will move forward in the grade level. When students are not successful, they will be pulled back a level or more to figure out where they are really reading at.
Currently, I have a fifth grader who is reading at second grade level and a fifth grader who is reading at 8th grade level.
That is why this is an excellent differentiated tool.
I much prefer this to RAZ for several reasons. 1) It is free 2) The feedback I get as a teacher is powerful to me. It does not READ ALOUD to the student so that means, that the student must be past an emergent reader.
I hope this is helpful!
