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. All facts presented in a factstrip or factbar are tested at least once on the page. Emphasis is usually given to the newest facts. Each page contains fact bars presenting and previewing the facts to be used on the page.
Worksheets follow a logical and thorough progression through the operation of subtraction.
Complete answer sheets are included. Although these pages may be used successfully for initial instruction in subtraction, they were designed as a review for students who had tried and failed with a traditional approach. Also included are color masters and small and large flashcard masters. This feature allows students who have not, or can not, master their facts to continue learning the process of subtraction.
