Dodecahedron Globe

Your task, if you choose to accept it will be to construct one of the Earth’s rarest figures…a platonic solid known as a dodecahedron. A dodecahedron is constructed from 12 regular pentagons and will need to be assembled with care. On each of the 12 pentagonal panels are the nets for 12 different geometric figures!

The 12 panels of the dodecahedron will be magnificently mathematic (as if you didn’t know that already).

STEP 1:

On the 12 pentagons you will need to identify the solid that would be constructed from the drawn net. You must determine what shapes are included in the net and also the number of faces, edges and vertices in the figure.

STEP 2:

Once you have completed your 12 panels, you will create a net for a dodecahedron. A net of a bunch of nets! Hurray! To construct the net, you can use the diagram below to help:

STEP 3:

Once your net has been created, double check it. You then can construct your very first Geometry and Spatial Sense Dodecahedron Globe.

Vocabulary Globe

Is there a better way to practice vocabulary than to build a dodecadehedron globe? I don’t think so. A dodecahedron is constructed from 12 regular pentagons (gosh, what are regular pentagons?) and will need to be assembled with care.

The 12 panels of the dodecahedron will be magnificently mathematic (as if you didn’t know that already). STEP 1:

On the 12 pentagons you will need to include definitions and examples for different geometric terms or illustrations of geometric formulas. First, generate a list of the 12 terms you plan to illustrate and get these approved by your teacher. This should be engaging, creative, and fun.

1. 4. 7. 10.

2. 5. 8. 11.

3. 6. 9. 12.

STEP 2:

You will create a net that could be used to build a dodecahedron. A little research could help. If you are desperate, ask your teacher.

STEP 3:

Once your net has been created (double check it), you will construct your very first Geometry and Spatial Sense Dodecahedron Globe.
