Nets

3
Nets A net is a pattern that you cut out and fold to form a 3 - dimensional figure.

4
Vocabulary Terms A cube is a prism with six congruent faces. Face

5
Vocabulary Terms An edge is a segment where two faces meet. Edge

6
Vocabulary Terms A vertex is a point where two sides of a polyhedron meet or a point opposite the base of a cone. Vertex

7
How many nets do you think you can come up with to form a cube? How many nets do you think you can come up with to form a cube? There are exactly eleven nets that will form a cube.

9
Nets for Pyramids have one base and lots of triangles. Sometimes they look like stars.

10
Are these nets lined up with the right 3-D shape?

11

12
What solid will this net form? Triangular Prism

13
What solid will this net form? Square or Rectangular Prism

14
What solid will this net form? Square or Rectangular Pyramid

15
What solid will this net form? Triangular Pyramid

18
Vocabulary Terms Prism – a A cylinder with polygons for bases (faces). All prisms are special cases of cylinders. FACE

19
Vocabulary Terms In a prism, these faces are called bases. You name a prism by the shape of its bases. BASE

20
Vertices Edges Faces The base has 3 sides.

21
Vertices Edges Faces The base has 4 sides.

22
Vertices Edges Faces The base has 5 sides.

25
A pyramid is a cone with a polygon for a base. All faces joining the vertex are triangles. They are named by the shape of the base.

26
Vertices Edges Faces The base has 3 sides.

27
Vertices Edges Faces The base has 4 sides.

28
Vertices Edges Faces The base has 5 sides.

End of Day 2 Prism & Pyramid Activity STOP!!

31
Special 3-D Shapes Cylinder Sphere Cone

32
Sphere Every point on the surface of the sphere is the same distance from the center The normal definitions of faces, edges and vertices are not appropriate for a sphere.

33
Cone The vertex of the cone is opposite the circular base of a cone. The cone has a face, a vertex, and an edge (formed by the base and the lateral face).

34
Cylinder A prism with two congruent, parallel faces called bases. A cylinder has 2 faces (circular bases), edges and no vertices.
