Entry Events
Events that will be used to introduce the project to studentsThe 150-Square-Foot 'Tape Out'
Students walk into a classroom where the floor is taped off into exact 150-square-foot rectangles. They are challenged to fit their 'daily essentials' (desk, chair, backpack) and a partner inside the perimeter and are asked: 'If you had to live here for a year, how would you rearrange the area to avoid feeling trapped?'Portfolio Activities
Portfolio Activities
These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.Blueprint Boss: Mapping the Footprint
Following the 'Tape Out' entry event, students will transition from a physical space to a technical drawing. In this activity, students act as lead architects to design the 2D footprint of their tiny home. They must stay within a strict 150-200 square foot limit while ensuring they include essential zones (sleeping, cooking, hygiene). Students will use graph paper to draw their plans, ensuring they utilize both rectangular and triangular spaces (such as a corner kitchen or a diagonal wall) to maximize efficiency.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA precise, to-scale 2D blueprint of the tiny home floor plan on graph paper, including labeled dimensions, perimeter calculations, and a total area breakdown by 'room.'Alignment
How this activity aligns with the learning objectives & standardsThis activity aligns directly with CCSS.MATH.CONTENT.6.G.A.1 by requiring students to find the area of polygons by composing and decomposing shapes into rectangles and triangles. It also addresses the perimeter concepts needed to define the 'micro-home' boundaries.The Net Master: Unfolding the Structure
Now that the floor plan is set, students must think vertically. In this activity, students will design the exterior 'shell' of their home. They will create geometric nets for the walls and the roof (typically a rectangular prism base with a triangular prism or shed-style roof). This stage is crucial because it helps students visualize how a flat drawing transforms into a standing structure, while providing the mathematical foundation for material calculation.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA set of flat, foldable cardstock 'nets' for the house's exterior walls and roof, labeled with the surface area of each individual face.Alignment
How this activity aligns with the learning objectives & standardsThis activity aligns with CCSS.MATH.CONTENT.6.G.A.4, as students represent 3D structures using 2D nets and use those nets to calculate total surface area. It also touches on 7.G.B.6 by dealing with composite 3D objects (prisms with triangular roofs).Surface Scientist: The Material Audit
As sustainable designers, students must now determine the 'cost' of their home—not just in money, but in resources. Using the surface area calculations from the previous activity, students will calculate how much siding, paint, and roofing material they need. They will research 'green' materials (like reclaimed wood or recycled metal) and calculate the total environmental impact based on the surface area they need to cover. They must justify their material choices based on sustainability and efficiency.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA 'Material Procurement & Sustainability Report' that lists total surface area, the amount of specific materials needed, and a rationale for why those materials were chosen for environmental health.Alignment
How this activity aligns with the learning objectives & standardsThis activity aligns with MS-ESS3-3 by requiring students to minimize human impact through material choice and resource efficiency. It also applies CCSS.MATH.CONTENT.6.G.A.4 to solve a real-world procurement problem.Sustainable Stylist: The 3D Build
In the final phase, students bring their math and sustainability research to life by building and 'staging' their 3D model. They will use artistic principles like light-colored interiors to create the illusion of space and strategically place windows for natural lighting. Students will assemble their nets into a final 3D model and add artistic details (solar panels, rainwater barrels, interior 'space-saving' furniture) that demonstrate their vision for a functional, eco-friendly micro-home.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA fully assembled, decorated 3D scale model of the tiny home, complete with interior and exterior artistic details that reflect sustainable living.Alignment
How this activity aligns with the learning objectives & standardsThis activity aligns with VA:Cr2.3.6a, as students design a structure in response to a specific need (sustainable housing). It also incorporates the psychological and artistic goals of making a small space feel functional and 'livable.'Rubric & Reflection
