MATH DITTOS 2: Fact Controlled ADDITION and SUBTRACTION for Special Learners is a unique tool for teaching addition and subtraction. It is a sequential, ground up approach to addition and subtraction computation with fact support, much like a controlled vocabulary in reading. Each page presents a limited number of problems with plenty of space to work out the problems on paper. The facts necessary to complete each problem are always presented on the page in a fact reference section. The pages can be printed and then completed by the student. The program also includes complete answer sheets.Both special learners and regular education students benefit from its thorough and systematic approach.MATH DITTOS is in Adobe Acrobat PDF format.
