This site has a range of activities for use with students with special needs. I have personally used a range of the printable activities for general use with Junior School classes. There are worksheets and printable resources for Maths and Literacy and links to free downloads for visuals. Worth a look if you haven't used it before.
Many of the printables can be laminated and used on repeated occasions in the classrooms. I have used the Shopping cards using dollar amounts, laminated and had the children fill in the change you would get.
