MATH DITTOS 2: Fact Controlled ADDITION & SUBTRACTION for Special Learners is a remedial, "ground-up" reteach of addition and subtraction. Addition & subtraction facts are presented in "Clusters," including the fact and its complement. Practice problems are controlled, or limited, to the clusters shown on each page, allowing for review of the facts, a prompt for unknown facts, and, most importantly, allowing the student to progress operationally even though facts are not mastered.

Cluster 17Each regular cluster includes only three numbers. For example, cluster 17 is comprised of 2, 9, and 11 only. Students quickly learn to look for the three-number pattern. Initial instruction can be enhanced with any manipulative. After initial drill, clusters should be completed and checked before completion of the page problems. Facts are presented sequentially, omitting the zeros, from the 1+'s to the 9+'s. Subtraction facts are included with their addition complement. A few examples are included here and there, as reminders only. These are guided practice sheets.

MD2:FCA&SfSpL is unique in that it is published as a series of Adobe PDF computer documents, and in that it supplies comprehensive fact support. Educators can now have a complete addition & subtraction workbook on their computer hard drive and run as many copies as needed. Students who have not, or can not, master their facts can continue learning the processes of addition and subtraction with fact control.

MATH DITTOS 2: Fact Controlled ADDITION & SUBTRACTION for Special Learners consists of 52 blackline worksheets and answer keys, color masters, flashcard masters, and no fact pages.
