![]() She gave them to me to decorate my first ever classroom.3D Modular Origami/Block Folding/Golden Venture Origami/Chinese Paperfolding is a branch of origami where the piece is not made out of one singular piece of paper, but made with many pieces, each folded the same way. My sister had built a sonobe cube and octahedron as a MathCounts student. (True Story – this happened to me during my first year of teaching. ![]() Warning – don’t hang these up unless you plan to let your students build them! They will bug you relentlessly until you give in. I printed the names on regular copy paper and glued them to colored cardstock. I am sharing the posters I created to hang under each model at the bottom of this post in case you want to create your own modular origami display. They make my math teacher heart so happy. A large metal washer would work better, but I didn’t have any in my classroom on the day I decided to hang these up. There is a binder clip inside each origami model that the fishing line is tied to. I used fishing line to hang my modular origami units from the ceiling. ![]() ![]() Then, they can take the two hexahedrons apart and form the cube. I often have students build two hexahedrons to begin with. The hexahedron is also known as “Toshie’s Jewel.” It only requires three units. They are the most straight-forward model to assemble. Then, take apart one of the corners and add in the additional three sonobe units.Ĭubes are definitely a student favorite. Usually, I tell students that if they build two cubes that they can take them apart and assemble them into an octahedron.įor the colliding cubes, build one cube as normal. The great thing about the octahedron is that it only requires 12 sonobe units. I recommend checking these videos out to learn how to assemble the larger units. There are some excellent YouTube videos that show various assembly methods. If you are wanting to make decorations for your own classroom, you can use 12″ scrapbook paper to make jumbo-sized origami models.įull Disclosure: It took me 9 years of teaching students to fold sonobe units to learn how to build the 30 piece icosahedron. I cut regular colored copy paper into 8.5″ squares for students to use for origami building. They also have a printable tutorial for assembling six sonobe units into a cube and a tutorial for assembly twelve sonobe units into an octahedron. I have printed these instructions and given them directly to students. Maths Craft New Zealand has a nice printable set of directions for folding a sonobe unit. While this origami book is an excellent resource, you don’t have to purchase it to learn how to fold a sonobe unit. From this book, I learned to fold sonobe units which can be assembled into various different modular origami pieces. Usually, I do origami as an end-of-year project.Īs a first year teacher, I purchased a copy of Unfolding Mathematics with Unit Origami. I also like that having them on display from day one will build student anticipation for when we finally learn to create them. Now that I have them hanging from the ceiling, students can see the names of the different origami models and how many sonobe units are required to build them. Some students opt to create additional sonobe units to create larger units. Almost every year, I make origami sonobe hexahedrons and cubes with my students. I created this classroom display to show off the different modular origami projects I have created over the years from sonobe units.
