Icosahedron Ornament Balls Tutorial | Math = Love

I ’ ve got an icosahedron decorate balls tutorial to contribution with you today. These ornaments are super easy and fun to build with fair twenty circles, glue, and some ribbon .

These ornaments can be made for Christmas or truly any time of year !
Icosahedron Ornament Ball I actually had a node teacher for this lesson .
My sister is studying to be an art teacher, and I know she is going to be a bang-up one. Her college semester ended a few weeks before the end of our school class, so she took this as an opportunity to come and visit my classroom and my students.

Icosahedron Ornament Balls Tutorial


To create these icosahedron ornament balls, you will need respective different supplies .

Circle Punch

The main add you will need is 20 circles per ornament that you want to create .
Scrapbook Paper Cut Into Circles If you are only making a single icosahedron decorate ball, you could credibly get away with cutting out your circles by hand. It will calm be a boring job, but it shouldn ’ t take you excessively long .
If you plan to do this decorate plan with students, you will decidedly want to invest in a traffic circle punch. My sister used a 2-1/4″ circle punch to punch out the circles for our ornaments .
2-1/4" Circle Punch Any size circle punch will work, however. Larger circles will produce larger ornaments. Smaller circles will produce smaller ornaments .

colorful Paper to Cut Circles From

My sister punched the circles we used for our ornaments out of random leftover scrapbook paper and photograph mat booklets .
If you have scrapbook newspaper already lying about, that is probably going to be the cheapest option .
Photo Mats and Circle Punch If you need to buy newspaper, my sister recommends these photograph mat booklets that you can purchase at Walmart for around three dollars .
She prefers the photograph mats to the scrapbook composition because the small size makes manipulating the circle punch much easier .
My baby and I primitively learned to make these icosahedron ornaments in our 7th grade pre-algebra class. Mrs. Sellers would have her students bring in a push-down list of old Christmas cards each year .
We would cut out our circles from these old Christmas cards and turn them into Christmas ornaments to hang on our tree .

Cardstock to Create Equilateral Triangle Template

You will need some cardstock to create an equilateral triangle template to match the size of your traffic circle punch. The points of the equilateral triangle should lie on the circumference of the newspaper circles .

Curling Ribbon

Each decoration will require a nibble of curling ribbon to create a hanger at the top of the decoration .
Curling Ribbon You can pick up a choice of unlike colors of curling ribbon at Dollar Tree. You could besides use regular ribbon if you already have that on handwriting .

Glue Sticks

The death provision you will need to have on hand to create an icosahedron ornament ball is some glue sticks. I prefer glue sticks for this project rather of liquid glue due to the fact that it dries much faster .

Preparing Your decoration Supplies

Make sure you have twenty circles punched for each decorate that you plan to create .
next, prepare your equilateral triangle template. The size of this template depends on the size of your circles .
The points of the equilateral triangle must rest on the edge of your circles .
Lay the template on acme of each circle ( blueprint facing up ) and begin folding over the edges .
After folding over two of the edges, it is normally easiest to remove the template before folding over the concluding edge.

This small step reduces the find that your triangles will not match up when gluing your icosahedron decoration musket ball together .
A little opening in the center of triangulum is fine. Gaps on the vertices of the triangles are bad .
pretty soon, you ’ ll have a voltaic pile of triangles. Remember, you need 20 of them !

Assembling the Icosahedron Ornament Ball

After lots of cutting and folding, it ’ south finally time to assemble our icosahedrons !
My sister made two partial pieces to demonstrate the construction process to my students. I thought this was a brilliant idea .
Top and Bottom Domes of Icosahedron Ornament Ball She ’ south going to decidedly make a bang-up art teacher !
first base, take five of your circles and glue them together to form a attic .
Top of Icosahedron Ornament Ball You are actually going to need to make a attic for the top of the ball and a dome for the bottomland of the ball .
The top dome needs a curl up ribbon hanger. Take a piece of curling ribbon, knot it, and place it in the center of the dome before gluing the concluding two triangles together .
then, build a like dome ( without the hanger ) for the bottom of the decoration .
After using five pieces to make the lead dome and five pieces to make the buttocks dome, you should have ten pieces left .
Glue these ten pieces in concert, inverting every early triangulum, so that the pieces form a line with a flat top and apartment bottom .
My sister glued five pieces together to demonstrate the process to the course .
The best way to go about this adjacent step is to turn over your long deprive of triangles and apply glue to the top or bottom of the strip .
then, begin attaching each firearm with glue on it to a section of one of your domes .
finally, add glue to the remaining pieces and attach the other dome .
My students were so excite to proudly display their finish ornaments .
Icosahedron Ornament Ball I had to join in on the playfulness and create my own icosahedron ornament ball. So fun !

Ideas for Adapting this project

If you wanted to make this ornament project more math-related, you could have students cut their circles out of colored cardstock and decorate each circle to reflect something that they learned this year .
You could take Tina Cardone ’ s Fan Posters Project and turn it into Fan Icosahedron Ornament Balls. Pass out set templates and have each student write affirming statements about their classmates on a r-2.

Sort the circles by student. then, have the students assemble their own decorate musket ball that is covered with words about them .
I could besides see this as a culminate geometry project. Each triangulum could be decorated with a different theorem ? Or geometric vocabulary word and illustration ?
possibly this could be turned into an natural process of geometric construction ? Use a ruler and compass to construct the necessity pieces without a template ?
