Results of a survey show that secondary school mathematics teachers believe that a geometry course plays an important role in mathematics education. Many respondents would support evolutionary change in the nature of the course, but few would favor revolutionary change. (SD)

An activity involving measurement of various parts of a bicycle is described. Sample worksheets are included. (SD)

Geometric analysis of a cube can motivate formulae for factoring algebraic expressions involving sums and differences of cubes. (SD)
