ab: Summary: This article describes a series of activities for
intermediate-level students to explore ratio reasoning using a digital
microscope. In the Common Core State Standards, this subject is
addressed for sixth- and seventh-grade students, although this type of
reasoning should be introduced at a younger age. Thus, the authors
designed this set of activities and then implemented them with a group
of fourth-graders. The lesson was well-received and established a
foundation for future development of ratio reasoning.
