| Geometry, the study of shapes in space and spatial relationships, offers students one of the best opportunities to relate mathematics to the real world. Spatial ability, or "spatial sense" can be improved through geometric activities. Spatial sense is essential in many tasks, such as writing letters and numerals, reading tables of information, following directions, making diagrams, reading maps, and visualizing objects that are described verbally. Learning experiences that involve constructing 3-demenional objects or using geo-boards help students explore and expand their geometric knowledge. |

| The fifth grade students have been working very hard at constructing pentagonal pyramids, rhomboids, and pentagonal prisms. As a challenge, they were given the pieces to the ninth stellation of the icosahedron. An Icosahedron is a solid that has 20 faces, each of which is an equilateral triangle. To stellate an object, the faces are extended until they intersect. There are 59 different stellations of the icosahedron; this is only one of them. The students colored, cut, taped, and constructed these relatively massive projects. It's almost miraculous to watch a two dimensional piece of construction paper become a three dimensional figure. Take a look at some of their marvelous creations, which were suspended from the ceiling in the TYROS room. |
