Polysolids adds another dimension to the classroom by encouraging students to create three-dimensional shapes, developing their spatial awareness. Whether working from the included activity book or engineering their own original structures, students will see how solids are positioned in space. To deepen the experience, teachers can ask them to draw their creations on graph paper and calculate their volume. This exercises critical math and geometry skills and provides excellent problem-solving opportunities. Set includes 44 durable wood pieces in 14 unique shapes, 8" x 6" grid board, and full-color activity guide. Grades 1 and up.
