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 students' prior understanding of the formula for the area of circles can be used to bridge other mathematical concepts.
