G9 Math: 3D shapes in a Service Action Project

In Grade 9 Math, we are applying our learning of surface area and volume of 3D shapes in a Service Action Project to design a better backpack for the Kuei Shan elementary students.


Our first step was to interview the elementary students to understand how they use their backpack and how they would improve it. Our next step will be to take their suggestions to design a blueprint for a new backpack.


Through applying concepts of mathematical modeling and 3D measurement, we hope to create precise backpack designs for the creators of the current Kuei Shan backpack to consider as a better design for our elementary students.
