### Unit Guide

## Introducing Computer Programming in a Traditional Classroom

## Guide Entry to 81.06.04

The mathematical topic included in the unit is the area of plane figures. Computer programs, of varying degrees of difficulty, are written in the BASIC language to enable students to calculate areas of plane figures by using the computer. Each program introduces a new technique, yet it is simple enough to be presented informally and to be understood by any student who has no prior knowledge of computers or programming. The material developed here may be used at several levels of instruction for the following purposes: (1) to teach the concept of area along with simple computer programming to middle school students, (2) to reinforce the concept of area and to introduce simple computer programming techniques to students enrolled in applied mathematics, consumer mathematics and basic geometry courses in the high school, (3) to teach the concept of area and computer programming in greater detail to high school students enrolled in a college preparatory geometry course. The unit is not intended to be a complete course in computer programming, but merely an informal introduction to it in a traditional mathematics classroom setting. Hopefully, the unit will ignite a spark of interest and arouse the curiosity of the students. They will be encouraged to explore the field in greater depth by visiting nearby computer centers, watching how the computer is used, and talking with the people who run it.

(Recommended for 7th and 8th grade General Mathematics, 9th grade Applied Mathematics, and 10th grade Consumer Mathematics and Plane Geometry.)
