Sharing Teaching Ideas.

Mathematics Teacher, v86 n1 p37-39 Jan 1993

Presents methods for teaching two mathematical concepts that utilize visualization. The first illustrates a visual approach to developing the formula for the sum of the terms of an arithmetic sequence. The second develops the relationship between the slopes of perpendicular lines by performing a rotation of the coordinate axes and examining the slopes of the resulting axes. (MDH)
