This math pack collection contains 24 multi-color plastic worksheets. Size 9" (23 x 23 cm.). Activities designed for working with square geoboards and also with isometric geoboards. Appropriate for discovering the ratio between surface area-volume, looking in greater depth and understanding the concepts of areas and geometric planes and associating the geometry contents with algebra and calculation. For square geoboards: basic topological notions are developed, lengths and surfaces are compared, segments are worked on, areas and perimeters and symmetries and notions of rotation are developed. For isometric geoboards: three-dimensional figures are constructed and figures in perspective
