Designing Zero Waste Patterns (High School)
This lesson engages students in designing a crossbody bag using all the material provided without waste. Students begin by envisioning characteristics of the bag that they want such as pockets, straps, and shape. Then, they sketch the pattern layout and optimize the use of “fabric” by strategically placing their pieces on chart paper, and conceiving ways to use scraps for decorative elements. Finally, students cut out and assemble a 3D model of their design in preparation for a runway show.
Lesson Objectives
1.
Students will be able to appreciate zero-waste techniques as viable examples of sustainable fashion practices.
2.
Students will be able to visualize the 2D components (nets) that make up a 3D bag.
3.
Students will be able to use reflections to reproduce geometric figures.
4.
Students will be able to optimize area by strategically placing pattern pieces on a pattern layout and consider how various shapes and edges fit together.
CC Standards
HSG.CO.A.5
Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software.
HSG.CO.B.6
Use geometric descriptions of rigid motions to transform figures and to predict the effect of a given rigid motion on a given figure.
HCD Process
Observe and understand zero-waste practices
Brainstorm and ideate designs that accomplish zero-waste
Create a prototype of a zero-waste cross body bag
