###### Math 4 - Act. 15: Making Nets for Solids
 Summary:This activity helps students relate cubes, cylinders, cones, and rectangular prisms to the two-dimensional shapes (nets) from which they were created. Main Curriculum Tie: Mathematics - 4th GradeStandard 3 Objective 3Visualize and identify geometric shapes after applying transformations. Materials: A variety of commercial containers in the shape of cones, cubes, rectangular prisms, cylinders Geo-solids (e.g., cubes, cones, rectangular prisms, cylinders) Additional Resources Geo-blocks Job Cards (Creative Publication) Jacket constructions grades 4-8 (Creative Publications) Background For Teachers:Nets are the two-dimensional shape that, when folded, would cover a three-dimensional solid.Intended Learning Outcomes:2. Become mathematical problem solvers. 3. Reason mathematically.Instructional Procedures:Invitation to Learn If we cut these containers at the seams what will they look like? Instructional Procedures For each cube, cone, rectangular prism, and cylinder, do the following: Take apart each box or container at the seams. Examine the two dimensional shape from which it came. Discuss how the net was made and the two-dimensional shapes that made it. Make a net that will fit the solid. Allow students to work with geo-solids (blocks) and make the net that would fit it. Extensions:Possible Extensions/Adaptations/Integration: Find solids in the world. Take a geometry hike and discover where and how solids are used in the building world. Homework & Family Connections Have students show parents how to make nets listed in the objective.Attachments Assessment Plan:Given any solid listed in the core, students should be able to make a net to fit. After the net is drawn, have students cut out, fold, and check it for fit.Author:Utah LessonPlans Created Date :Aug 29 2003 09:03 AM
