Euclidean Shards - Fraction Prism Math Manipulative

thingiverse

I recently attempted to print these fraction prisms but found that the fit was off. Feel free to modify them and share updates; I'm uncertain when I'll have time to revisit this project. The fraction prisms, named Euclidean Shards, were designed for the MakerBot Academy Math Manipulative Challenge under #makerbotacademymath. They resemble shards and were inspired by the Euclidean Algorithm, which calculates highest common factors. The goal of these 3D-printed objects is to teach students fraction addition and subtraction while utilizing 3D space. Additionally, they aim to be visually appealing. Each prism side represents a fraction of a foot, with three shorter sides that are consecutive halves of the longest side. The base isosceles triangle has one shortest side and two shorter sides. For example, a 1/3 shard has a 1/3 feet side, 1/6 feet side, and 1/12 feet side. The base isosceles has a 1/12 feet side and two 1/6 feet sides. By arranging these shards, students can solve fraction problems through trial and error or by using the shards to confirm their answers. In addition to teaching fractions, the Euclidean Shards help with measurements since they are all fractions of a foot/12 inches. They are stackable and include case files for storage. To print the full set, follow the provided quantities for each type of shard and case parts.
