For this worksheet, students have to weigh the desire to create a sustainable and environmental sound house, while sticking to a budget. They will have to balance a list of factors, including cost, energy efficiency, and aesthetic appeal, and will quickly learn that (at least in this case) it’s not possible to have it all, and tradeoffs must be made.
Students who will struggle with the math needed for this worksheet (4 digit addition and subtraction and 2 digit multiplication) can be given a calculator.
Students who finish the worksheet early can be encouraged to look at real world examples of these decisions by looking up material costs online. For example, they might compare the relative costs and merits of wood vs hardwood, vs composite decking at www.bunnings.com.au.
