We use to use Saxton math for our special education students but due to not passing the state standardized tests we now have to use Everyday Math just like the general educaiton

We do have a textbook series in the school for all grades, but we aren't compelled to use it. Some use it exclusively, others not at all. We have complete freedom to use whichever resources we want to.

We have to use Everyday Math as of this year. I still have my Investigations books, so I also checked that. I also use Marilyn Burns and other resources I have in my closet.

We, like MrsC have a Math textbook series (Math Makes Sense) that we can use, but we are not tied to it.

We have been given Harcourt Math for our on grade level students and SRA Number Worlds for our below grade level students. I have the option of using alternative materials.

We don't have to use a specific program. I was given 2 text books, which I use as a personal resource and guide, but I am free to teach and assess however I choose. Maybe this is a Canadian thing?? I notice the other posters that said this are also teaching in Canada!
