Making Scale Models Using a 3D Printer In this two- or three-day lesson, students will learn to apply their skills and understanding of scaled mathematical relationships to create a scale model of an object using either 3D modeling software and then a 3D printer or by measuring and building an object out of cardboard. BC Curricular Connections: Mathematics 9: Similar shapes have proportional relationships that can be described, measured, and compared. ADST 9: Complex tasks require the sequencing of skills; Complex tasks require different technologies and tools at different stages. Required background knowledge: Students should already have learned the mathematical calculations required in scaling dimensions, but they will review it in these lessons. This is a great project to finish a unit on scale and proportions. Lesson Plan Tools: Projector connected to device with internet access iPads for students with the Measure app Computer for each student with internet...
