Calculus may seem to be quite dismal to some, but it comes alive through the fine work of Gabriela R. Sanchis. Sanchis wrote this excellent piece on teaching calculus by drawing on the historical evolution of some of its key concepts. With support from the National Science Foundation, she also made sure to include several interactive Java applets which educators can use in the classroom. This piece is part of the Convergence math collection, offered by the Mathematical Association of America. These materials can be used in conjunction with other activities, and visitors may also use an embedded link to send the piece to a colleague.
