Fact Controlled
SUBTRACTION
for Special Learners

MATH DITTOS 2: Fact Controlled SUBTRACTION for Special Learners is a group of computer worksheets designed to allow students to compute while learning their facts. The fact bars, strips, etc. included on each page include all and only the facts used on the page. The worksheets are designed to be as uncluttered as possible, with large numbers and very few problems on each page. Fact support is included on all pages. These pages were not designed for initial instruction in subtraction, but as a review for students who had tried and failed with a traditional approach. While I do use these materials now for some initial instruction in subtraction, their best use is still as a reteaching material. MATH DITTOS 2: Fact Controlled ADDITION & SUBTRACTION for Special Learners provides a much more comprehensive approach to initial instruction.

There are no unsupported fact pages in the basic worksheets. While transition to subtracting without fact support is a goal of this program, that level will occur at different points for different students. There are lots of materials that can be used for that purpose. Almost all of the commercial materials available are not fact supported. That's why the MD2 series was written. All facts presented in a factstrip or factbar are tested at least once on the page.

Word problems accompany each fact page. The word problem pages carry the same page number as the preceding page with a "W" appended to the number. They follow the same facts as their companion page, and are intended to be used together.

MD2:FCSfSpL is unique in that it is published as a PDF computer document. The Adobe PDF format requires only the free Adobe Acrobat Reader. Navigation through the pages and printing are easily accomplished. It is also unique in that it supplies comprehensive fact support. Fact control allows students who have not, or can not, master their facts to continue learning the process of subtraction.

The PDF format registered version of MATH DITTOS 2: Fact Controlled SUBTRACTION for Special Learners includes 28 basic worksheets, 28 word problem worksheets, and complete answer keys.
