Abstract
Alice, a fifth grader who participated in twelve weeks of a teaching experiment on integer addition and subtraction, produced drawings as part of her strategy for solving integer addition and subtraction open number sentences. The drawings she created during the twelve weeks of the teaching experiment were analyzed and grouped into the following categories: Single Set of Objects, Double Set of Objects, Number Paths & Number Lines, and Number Sentences. These drawings provide insight into how children may directly model or count when solving integer addition and subtraction problems.
