This activity sheet has 15 conceptually based questions on the using the sigma notation, approximating the area of a bounded region and using limits to find the exact area of a bounded region. In one question, students are required to communicate their understanding of how their approximation compares to the exact area. The questions are designed to be used with Advanced Placement Calculus students.
You will find many other activity sheets for calculus available in my store. Some of them can also be bought in bundles.
