A "Geometry Net" is a flattened out
solid (a three dimensional shape) -- like a cube, a prism or a pyramid.
When you cut out the "net", fold it and glue it together you can see what
the three dimensional shape looks like.
A three dimensional shape is called three dimensional
(or 3D) because it has three dimensions: length, width and height.
The two most common measurements we need for a three
dimensional shape is:
- volume: for example, how much water it would
- surface area: for
example, how much area you would have to paint to cover the entire
outside of the shape
Creating paper models like these geometry nets allows children to explore the more
familiar 2 dimensional shapes that go into making a three dimensional one.
I think it's particularly fun to do these during
Christmas -- you can hang the three dimensional shapes on the Christmas
By Shape - Platonic Solids (all the sides are identical):
By Shape - Prisms (a 3D shape where if you sliced it like a loaf of bread,
each slice would look identical):
