ab: From the text: The topic of limit, in addition to being an important
mathematical concept, is also a significant stumbling block for many
students. To introduce the idea of limit, some activities from the
regular middle school math curriculum can be extended to give students
a picture of the concept and provide a preliminary frame for the
symbolic treatment that will be found in later classes. This article
demonstrates how studentsâ€™ prior understanding of the formula for the
area of circles can be used to bridge other mathematical concepts.
