Lesson 17: Wrap Up Your Sculpture
Time: 60 minutes
Materials: Lesson 17 video; The Daily Doodle notebook; Cardboard kits; glue and tape; Harvested and donated wrapping paper, buttons, fabric, etc.
Overview: Students wrap their head around the surface area of 3D shapes, and wrap-up their sculptures.
They learn that the surface area of an object is the total space that wraps around its outside. Basically it’s the sum of the areas of surfaces on a 3D shape. Students learn that they can measure the surface precisely using a ruler or tape measure, or if they don’t have a ruler, they can estimate the measure of a surface using a part of their bodies.
Students start by calculating the area of the 3D cube they assembled, based on their previous measurements, using SA = 2LW + 2LD +2DW where L = length, W = width and D = depth. They attach the cube to their sculptural headdresses, exploring where it might naturally fit. Students practice using estimations and formulas to calculate the surface area of parts of their headdresses. They either estimate the quantity of materials they used to cover the area of their headdresses, or they calculate the surface area of a part of their headdress.
