Project-based Learning: Soda Can Redesign, a Lesson on Volume

Project-based Learning: Soda Can Redesign, a Lesson on Volume

Comments 0 Comment

This is a fun lesson I do with sixth graders where students redesign the soda can. After reviewing volume of rectangular prisms, students determine the volume of a can of soda in cubic inches. They use this volume to re-design the soda can so that their can has the same volume. Students will need to use the area of polygons such as rectangles, triangles, parallelograms, and trapezoids in the design of their new can. They begin by creating a net…

This is a fun project I do with fifth graders where students take on the role of Senior Designer at Packagings R Us.

An extension is to have students do a cost analysis for…

My son came home with this project in the third grade and I thought it was brilliant! But then, I was reminded of his third grade teacher, Mrs. Durbin, and it made sense. She understands how to teach mathematics effectively and is always doing fun, hands-on activities and projects with her students. For this project, Mrs. Durbin was working with her students on the concept of area. Students created a design on inch graph paper and then indicated the total…
