Tessellations' Geometrics sets are made of durable, nontoxic, and quiet foam and contain lesson material for a range of grade levels.
Conic Sections
This set contains four cones cut four different ways to reveal the different conic sections - circle, ellipse, parabola, and hyperbola. Four reproducible worksheets cover various properties of the conic sections, including their descriptions using Cartesian and polar coordinates, their foci, and their eccentricity. Cones measure 2-3/4" across the base and 4" in height. Grades 7-12.
Fifteen different foam geometric shapes. Angles and edges are labeled on the frontsides to facilitate classroom discussion. The names of the shapes and their areas are printed on the backsides. The thickness of the pieces is 0.2" (0.5 cm), and the circle diameter is 4" (10 cm).
