As with the Addition Skills workbook, this too has a task analysis outline that provides the teacher with exact knowledge of where to place students who are either starting into the process of learning subtraction or those who have acquired some knowledge of this basic math function. The subtraction outline has 51 steps which provides teachers with the level at which each student has obtained baseline and to add sequential steps so students can successfully master all levels of subtraction skills.

Complete task analyses allow the instructor to utilize the worksheets and assessments to guide students from primary subtraction skills to higher level thinking skills.
