How do the characteristics of problem situations impact the development of the students' conceptual understanding of addition and subtraction?
Participants will explore the use of counters, grouped manipulatives, and graphic organizers as tools to join and/or separate sets. The activity explores the effectiveness of various concrete manipulatives and graphical representations for representing addition and subtraction problems that have different characteristics. The problems are built on an instructional sequence that promotes student understanding of addition and subtraction concepts and leads to effective instructional design.
