Investigating Mathematics with PentaBlocks.
Berman, Sheldon; Plummer, Gary A.; Scheuer, Don
These classic pattern blocks were introduced in the early 1960s as part of the Elementary Science Study materials developed by the Educational Development Center (EDC). The six classic shapes share one common characteristic: all of the angle measurements are multiplies of 30 degrees. Shapes include the regular triangle, square, and hexagon; the isosceles trapezoid or "half-hexagon"; the 60-degree and 120-degree rhombus; and the 30-degree and 150-degree rhombus. This book contains 20 sequential activities which involve perimeter and area, angles and similarity, and symmetry operations and tiling. (ASK)
