CIRCLES AND CURVES by Arthur G. & K. G. O. Watts Razzell


Email this review


Maintaining the style of Symmetry and others in the series, this is action-oriented. In the case of exploration of the circle, a little background history is presented and numerous activities help the reader to identify the shape, reach a reasonably refined concept and explore some of the properties. Other curves such as the parabola, the ellipse, the spiral and the helix are presented in the form of activities enabling the child to identify and reproduce the shapes; little investigation of these more complex shapes is provided. It could be an interesting way to spend a weekend.
