| Part 1: Presenting and Checking Warm-Up Problems [Begin: 02:12]
|
The lesson begins with the teacher asking the students to solve "warm-up"
problems displayed on the overhead projector. The problems include finding the largest
integer n for which 2 >n! and finding the number of cubic inches in the volume
of a rectangular solid if the side, front, and bottom faces have areas of 12 in.,
8 in., and 6 in. respectively. Students work on their own, during which time the
teacher moves around the classroom helping individual students. After about thirteen
minutes the teacher reconvenes the class to share the solutions. The teacher asks
students for the answers which she records on the transparency. For the last problem,
she asks, "How did you get it?" and the student describes the process. |
