Weird Dice

Students Craft Bizarre 3D Cubes, Showcased in Photo Below. Print Settings: Printer Brand: MakerBot Printer: MakerBot Replicator Notes: Some files will need adjustments before printing to ensure they can be printed successfully. Designing This Project: Find a Tool. Locate an application or software that allows you to create 3D print files. Our district is 1-1 with iPads, and I struggled to find a suitable app. However, I discovered Morphi, which enables users to place objects in space and manipulate them for 3D printing. Any other tool can be used. Give Directions to Students: The only rule is that the cube cannot resemble a standard dice. It doesn't matter how it looks, but it must have curved edges. Some students combined a pyramid on a cube, making it no longer a dice. Others included rounded figures and made it their own unique design. Check the Files: Some of my students' objects were floating in mid-air, so we worked together to remove them and position them correctly for 3D printing. Students Print Their Files: I had students print their own files, but some didn't turn out well because they weren't positioned properly on the table. Custom Section: Project Name: Bizarre Cubes Overview and Background: Our school's students struggle with probability concepts. We start by learning about theoretical and experimental probability. Students will learn the differences between these two probabilities and be able to think critically about geometrical probability. Objectives: Students will use theoretical probability. Students will use experimental probability. Students will apply geometrical probability. Subject: Math Audiences: 7-12th grade Skills Learned: CCSS.MATH.CONTENT.HSS.MD.A.1, CCSS.MATH.CONTENT.HSS.MD.A.2, CCSS.MATH.CONTENT.HSS.MD.A.3, CCSS.MATH.CONTENT.HSS.MD.A.4, CCSS.MATH.CONTENT.HSS.MD.B.5, CCSS.MATH.CONTENT.HSS.MD.B.6, CCSS.MATH.CONTENT.HSS.MD.B.7 Lesson/Activity: Students create a bizarre cube and 3D print it. Before printing, have students use geometrical probability to find the probability of each side landing face up. 3D print each cube. Students will physically roll each dice 100 times to determine the experimental probability. Students will write a 1-page paper comparing theoretical and experimental probabilities. Students will present their findings to the class. Duration: Including time for our probability unit (12 days), and just for this project (6 days). Preparation: Students should be familiar with theoretical and experimental probability. They should also know how to find geometrical probability given a shape. References: Bizarre Cubes Rubric and Assessment: Students should have printed their 3D cube, calculated the probability of each side landing face up, analyzed the differences between theoretical and experimental probabilities, written a paper comparing similarities and differences, and presented that paper to the class. Handouts and Assessments: Attached is the rubric.
