Conceptual-How does perspective influence representation of 3 D shapes in a 2D plane? Debatable-How might we determine which representations are most economical? Task Outline: Imagine you are architects who have just won a contract to build home sites on a new estate down the road from Linden Park Primary School. Your task is to find all possible combinations of four block (cube) houses. You then need to cost your designs and produce a new housing estate poster showing where the houses will be built and their total costs. Design Brief: Four Cube Houses Congratulations!! Our company has won a contract to supply modular houses made of four cubes to a new housing estate. The construction rules are: all cubes are the same size. Cantilevers are not permitted all cubes touch face to face (not like in our logo). there are no 'cantilevered' structures. all the houses must be different, ( ie: cannot be transformed into each other by a simple rotation, reflection or translation.) 1. Your task is: Design as many four cube houses as possible. Record the number of faces, edges and vertices for each model. Draw each house on isometric dotted paper. Work out the total construction cost of each design using these figures and record all working out: o Floors: - ground floor $3000 - first floor $5000 - second floor $9000 - third floor $12000 o $1,000 for each square unit of external wall. o $2,000 for each square unit of roof. 2. You now have an isometric drawing of each house design and its cost. On an A3 sheet of grid paper: draw the streets for the new housing development estate mark out 15 blocks of land and calculate their cost according to $10,000 for each square unit of land in the sub-divided block redraw and cut out the isometric drawings and glue them to each block make sure the costing of the house and land package is written in as a 'price tag' (house price plus land cost) add commentary about the attractiveness and features of each house. See examples below: This design keeps the resident fit because the kitchen is on the top floor. You save on lawnmowing costs with this geometric beauty. . present the whole poster for class display. 3. Reflection: What mathematical concepts were used in this investigation? What mathematical techniques or methods did you use to complete this task? How accurate are your results and how can you verify this? Explain how the mathematics used in this activity connects to the real world. 4. Extension task for those who like a challenge Use x blocks to build a house worth $100 000.
