SPIRALS

Only one concept is introduced here but if a definition of spirals is what you want to get across, putting children through the Sitomers' paces should do it. Readers are asked to roll clay into strips to demonstrate the difference between circles and spirals, look at a phonograph record and speculate on what would happen if the grooves were circles, look for spirals (and spatial spirals, or helixes) in nature, test the advantage of a screw over a nail, and draw spirals on squared paper or trace them with chalk on the sidewalk. Supplementary exercises.
