Quick Overview

Problems like “3 + 6” and “0 + 9” may seem easy, but they probably cause a few anxious moments when students first learn them—especially at an automatic level.


To counter the confusion often encountered when moving from addition to subtraction, students need to understand what subtraction really is. To do this, Subtraction Facts 0 to 9 takes students through the concrete-representational-abstract learning sequence. At the concrete level, students learn to solve problems like 7 – 3 by counting out seven objects, removing three objects, and then counting the remaining objects. At the representational level, students learn to draw pictures of objects next to a problem and use these pictures to determine the answer. Finally, at the abstract level, students use numbers alone to answer the problem, or, if they’re unable to recall the answer, draw out the problem using tallies.
