Focus on Geometry

by Margaret Smart and Mary Laycock

Focus on Geometry leads students through a careful sequence of hands-on activities to discover, formulate, and apply rules for area and perimeter of rectangles. These rules are extended and modified for the parallelograms, triangles, trapezoids, and circles in the same hands-on discovery style. The last part of the book provides patterns and activities for making models and directing students in experiments. From these, formulas for the surface area and volume of rectangular, cylindrical, conical, and spherical solids take on meaning.
