This set contains twelve wooden geometric solids. These solids represent common 3-dimensional shapes frequently seen by students and discussed in the mathematics curriculum in textbooks. \n \nGeometric solids are thought of as a resource for senior primary and high school but the shapes should be used in all grades to develop various geometric concepts and relationships. \n
Wooden Geometric Solids Suggested Activities
\nMATCHING Early experiences should include distributing the solids to the students and having them name or list objects in the room that are similar to the solids. \n \nCHARACTERISTICS Students should separate the solids by various characteristics: those with only flat surfaces, those with only curved surfaces, those with a specific number of corners, those that roll, those that have the same shapes on the top and bottom etc \n \nVOCABULARY As students progress they should develop appropriate vocabularies and separate the solids using these terms: number and type of faces, number of vertices, number of edges, prisms, pyramids, type of base. \nAs students gain experience with this set relationships of various solids should be explored. Students can be given two solids to compare and be asked to write down the similarities and differences. \n \nMEASURING When students are able to identify faces, edges and vertices they can begin measuring various dimensions of the solids. Use of the solids will help reinforce the concept of height (altitude) by providing a physical model showing that height is not always one of the edges. It must be measured perpendicular to the base of the solid.
