## Sustainability Education Principles

## Pedagogical Approaches

This ESD unit places mathematics at the forefront of a comprehensive critical thinking project. Students must design a “green” building, applying both math skills and sustainability principles. The goal of the resource is to increase awareness of sustainability while using and applying mathematics in a real-world context.

Students design a 1200 square foot house, keeping their budget under $240,000. Math topics covered include fractions, decimals, percent, central tendency (mean, median, mode), measurement, area of 2-D shapes, spatial relations, scale, estimation, unit conversions, graphing, and financial math. Throughout the lesson sequence students analyze the economic, environmental and social implications of their lifestyle choices and of their construction plans. They also learn to calculate interest on a bank loan, practice measuring and converting measurements used in designing floor plans, and analyze the cost of different types of construction materials. Students create a final budget and build a 3-D model of their house.

Each lesson can be delivered in a “stand alone” fashion to introduce or supplement individual math outcomes **or** the entire unit can be implemented in sequence throughout the year to support the existing curriculum. Students can create a “Design portfolio” and collect/compile their project work as the activities relevant to the math curriculum are completed.

Lesson One: Whose House? (3 X 60 min.)

As the first step in designing their “green” houses students view a Power Point Presentation showing the homes of various celebrities. This activity begins the discussion of sustainability and social equity.

Students are then introduced to the requirements, expectations and assessment methods of the project. They complete a concept map of their dream home along with a specifications sheet and a math skills concept map.

Lesson Two: Intended Occupants (optional)

This lesson is a quick math literacy activity which asks students to envision and describe the people who will live in the house they design.

Lesson Three: Leave Only - (2 X 60 min)

Students consider how their everyday decisions impact their futures and those of generations to come by analyzing consumption patterns and calculating ecological footprints. After sharing their findings, students illustrate their footprint calculations in graphic format.

Lesson Four: Design Graphic- (1 X 60 min.)

Students use a decision-making graphic to weigh the environmental and economic impacts of two houses, one made of straw bales and one made of wood timber. Students then calculate means for the rating scale on both the economic and environmental criteria. They communicate this data using their choice of bar graphs, line graphs, pictographs or pie charts.

Lesson Five: All A Loan. Pt. 1- (1 X 60 min.)

Students calculate the percentage of each color of M&M candy found in a bag of M&Ms, and communicate this on a bar graph.

Lesson Six: All A Loan. Pt. 2- (1 X60 min)

Using the percentage of one color of M&M candy as an interest rate, students calculate the principle interest to be paid on a bank loan to finance their house.

Lesson Seven: Measurement Madness – (1 X60 min.)

After a brief introduction to the ways and means of measuring and converting units using equivalent fractions, students complete a measurement chart which converts inches to ½ inches and ¼ inches.

Lesson Eight: Scale the Wall- (2 x 60 min)

Students brainstorm what tools and skills an architect would use to create a floor plan. They are assigned classrooms within the school to measure. After first estimating the area of the rooms, the lengths and widths are measured and students create scale floor plans using graph paper.

Lesson Nine: Hit the Deck - (3 X 60 min)

After reviewing how to determine the perimeter and area of rectangles and triangles, students are given floor plans and asked to determine the areas of these composite shapes. They are then asked to draw floor plans for rectangular, triangular, and circular and parallelogram-shaped decks of specified areas.

Lesson Ten: Drafting Bubbles- (2 x 60 min.)

Students develop a series of potential house plans estimating the square footage and spatial layouts of the rooms. Using graph paper and draft design sheets students design their “green’ home.

Lesson Eleven: The Final Floor- (2 X 60 min)

Using proper scale and the skills associated with linear measurement, students draw the final floor plan for t their house, incorporating the required specifications.

Lesson Twelve: Greenhouse- (2 X 60min)

Students complete a construction estimate list and calculate the cost of required materials. They must research material options for foundations, walls, windows, roofing, and heating and cooling systems in terms of their environmental and economic implications. They then share this information in a jigsaw activity. Finally, students calculate the total cost of their design.

Lesson Thirteen: Thermal Resistance Activity- (1 X60 min.)

In this simple hands-on activity, students will learn what the ‘R=value’ means in energy efficient design.

Lesson Fourteen: Final Budget- (2 x 60 min)

Students calculate their final budget costs, taking into consideration the materials / construction costs and sales tax. They also must write cheques and balance their transaction register.

Lesson Fifteen: Build-A-Math (3 x 60min.)

Students will calculate how much of the building material is needed to create a 3-D structure and then build the structure to scale.

- No authentic action project
- No suggestions for differentiated math activities for those students working below grade level
- The metric system is not used in calculating areas or in measuring activities
- Activities are time intensive
- There are many paper handouts required which may be seen as a small contradiction to Green Principles.

This resource can be implemented as either a stand alone unit linking math, science and broad based technology curricula, or as a yearlong math project with embedded skills, supporting the math curriculum taught in the classroom. This second choice is best suited for addressing outcomes in Grade 6 or Grade 7 math classes. This ongoing math portfolio would culminate in the final building project.
