Making Comparisons: Ratios. Topical Module for Use in a Mathematics Laboratory Setting.
Andersen, Lyle; And Others
The objectives of this module on making comparisons and ratios include using ratios to compare sets of objects and expressing ratios as decimals or fractions in lowest terms. The module provides six experiments. An envelope of manipulatives accompanies each of the first three experiments. The fourth experiment requires a multispeed bicycle. The fifth experiment requires the building of a gearboard. As an optional experiment, the student may be involved in small group work with a deck of cards. The module contains three enrichment cards which involve students in "real-life" problem situations. It also contains directions for utilizing a programmable calculator or computer. (Author/MK)
