Title: Assignment: (PBL) Scale Room Model Project
Course: HBUHSD Geometry Resource Course

Description: Students will make a scale drawing of one room in their home. Drawing will include at least 5 pieces of furniture. Students will make a rough sketch, demonstrate calculations for scaling room and furniture, make a final scaled drawing, and write a reflection paragraph

Teacher Directions: Give this to students as a cumulative PBL assignment.

Student Directions:  You will make a scale drawing of any room in your home (bedroom, living room, etc.). You may make the drawing as detailed as you want, but it must fit on 8.5 x 11 inches graph paper.

You will be assessed on the following:
Mathematics of the task:1. A rough sketch must be provided labeling the actual dimensions of the room as well as the actual dimensions of at least 5 objects in the room. Objects need to be accurately measured. Measure to the nearest inch and then convert to inches. (For
example, 5 ft 4 in = 5(12) + 4 = 64 in.).
2. Choose an appropriate scale factor and use the same scale factor throughout the entire project. Remember, the drawing must
fit on an 8.5 x 11 inch piece of graph paper.
3. Use the conversion sheet provided to show how you converted from real-life measurements to your scale drawing. Make sure
to label each conversion with appropriate units.
4. Provide the area of the original room, the area of the scale drawing. Calculate the ratio of the Scaled area to the original area.
How do this relate to the scale factor you used for the drawing.

Student time: 2 hours
