Which measurements would you need in order to draw a scale floor plan of your classroom? List which parts of the classroom you would measure and include in the drawing. Be as specific as possible.
Trade sketches with a partner and check each other’s work. Specifically, check if any parts are missing or incorrectly placed and write down your notes here:
After you have returned their work and revised your sketch as needed, discuss with the partner or with a group and agree on answers to the following questions. [br][br]Which classroom features must be measured and which are optional?
Which units should be used?
How will you record and organize the measurements (on the sketch, in a list, in a table, etc.)?
How will the measuring and recording work be shared? Agree on the role each group member will play.
Now, determine an appropriate scale for your drawing based on your measurements:
If the flooring material in your classroom is to be replaced with 10-inch by 10-inch tiles, how many tiles would it take to cover the entire room? Use your scale drawing to approximate the number of tiles needed.
How would using 20-inch by 20-inch tiles (instead of 10-inch by 10-inch tiles) change the number of tiles needed? Explain your reasoning.
Trade floor plans with other students. Discuss your observations and thinking. Based on your discussions, record ideas for how your floor plan could be improved.
