A Net is a two-dimensional figure that can be folded into a three-dimensional object.
Sample Geometry Learning Goals
- 2-D representation of cube, cuboid, cone, cylinder, prism and pyramid,
- identifying nets of the following solids ∗ cube, ∗ cuboid, ∗ prism, ∗ pyramid,
- identifying the solid which can be formed by a given net,
- making 3-D solids from given nets. Exclude nets of cylinder and cone.
A net is a two-dimensional figure that can be folded into a three-dimensional object.
11 Nets of Cube for Primary Math by Loo Kang Wee and CH Thong
according to http://donsteward.blogspot.sg/2013/05/nets-of-cuboid.html there are 54 ways for nets of cuboid to form a 3D object.
Ways to identify "non-net" of cube
- have more than or fewer than 6 squares
- the squares overlap
- 4 squares share a common vertex
- 2 squares lie on the same side of a centre row of 4 squares
- having more tahn 4 squares in a row
- by Net of A Cube ETD to go
