                   CREATING 2 DIMENSIONAL NETS FOR 3 DIMENSIONAL SOLIDS (Recognizing the links between 2D and 3D) NCTM Principles and Standards - Ref Page 169 (Geometry - Grades 3 to 5) MATERIALS REQUIRED PER STUDENT OR GROUP 10 Squares of same color 20 Triangles 4 Triangle Frames Plus Connectors PART ONE - Nets of Cubes 1. Make a 'T' shaped net with 6 squares, then fold it to create a cube. 2. See how many different nets you can make for a cube - Fig 1 PART TWO - Nets of Cuboids (Rectangular Boxes) 3. Make a 'T' shape with 10 squares (double row), then fold it to create a cuboid. 4. See how many different nets you can make for the cuboid - Fig 2 PART THREE - Nets of Pyramids 5. Make a large triangle with 16 triangles, and then fold it into a pyramid. 6. See how many different nets you can make for the triangular pyramid - Fig 3 PART FOUR - Some other nets 7. Make a net with 8 triangles. Find out what solid 3D shape it transforms to - Fig 4 8. How many faces does it have ? This one is called an octahedron (octa means 8). 9. Is it a regular octahedron ? Why ? 10. Discover what other nets you can make from this shape. [Klikko Math] [Klikko Science] [Product Information] [Product Comments] [Enquiries & Ordering] [Home] [Key Value Points]
