Have you ever seen a stellated dodecahedron? They are pretty awesome shapes. We have made some other 3-d shapes in the past and I though this would be a fun one to attempt. I even created a printable template for you to use to make your own! This is a beautiful combination of math and art!
A stellated dodecahedron is a 12-pointed star. Each point is a 5-sided triangle or pentagram. You make 12 individual triangular pentagrams and attach them together to create this amazing star shape.
My kids and I are proud of our creation and had a lot of fun building it! We colored all of our points, but it could be much simpler to print them with different colors. Card stock is best to use to make it stronger, but it does not have to be used.
How to Make the Stellated Dodecahedron:
To make it, print out the template (found in my subscriber library). You will need 12 copies of the page. We did it on white card stock and colored all of them with fine point Sharpies. You could also print it on a variety of colors of paper which would look amazing, too! If you are doing it in a classroom setting, let the kids each have a triangle to decorate.
My daughter and I loved coloring it together.
Then cut out each piece long the solid lines and fold on the dotted lines.
Attach each triangular piece to another one by the flaps. I found it quickest and easiest to use a small piece of clear tape on the inside and then again on the outside. This held it together the best.
As you get to the end the taping is trickier, but I could do the inside of all except the last flap or two.
Fun isn’t it?

November 11, 2019 at 10:36 amI printed out your stellated dodecahedron template last year for book re ports and the kids loved them. But I can’t find the template!!! Could you please tell me where it is on your website??

December 3, 2019 at 3:19 pmI just made mines for I love it! I shrunk it a bit so I can fit 4 on a page. I will only need to print out 3 pages per student. We are going to make large holiday ornaments in my math class. I used double sided tape and it worked fantastic. A little wider than the tabs so I think I will have the kids cut it in half so one piece can be used on two tabs.
