Introduction: A cubeThis is a cube.A single cube is called a unit cube. face edge
Same number of units cubes with different arrangementsDid you notice that all these solids are made of3 unit cubes but they are arranged differently?
Count the number of unit cubesHow many unit cubes are used to build this solid? 7 unit cubes
Build Your Own SolidsUse 4 unit cubes to build as many different solids asyou can. You may use Lego bricks (if you have them athome) or click on the url below to build your solids. http://illuminations.nctm.org/ActivityDetail.aspx?ID=125 Once you are at this website, click on this to learn how to use the tools to build your solid.Source:NCTM Illuminations
