Step I: Make a Decision
1. Choose a class
2. Ask the teacher for permission to use their class
3. Determine a recurring behavior – for example:
a. answering questions
b. taking notes
c. checking the clock
4. Determine a set time frame – one class period, 20 minutes, a week of classes
Step II: Make a Sketch
5. Sketch a map of the classroom
6. Gather your data by placing a dot that corresponds to the desks in which the behavior
occurs
Step III: Make a Final Drawing
7. Find the dimensions of the room, student desk, teacher desk, and door.
8. Use an 8 ½ x 11 sheet of paper
9. Determine the scale – the ratio of the mapped size to the actual size. Worksheet on
following page.
10. Apply the scale to the room, door, and desks.
Step IV: Make an A
11. Did you map a recurring behavior?
12. Do you have a nice looking, neat map?
13. Do you have all of the components that a map should have (refer to your notes)?
Scale
1.
Determine the length of one side of your mapped classroom. Measure it. Include the
unit of measure.
2. The actual length of the room and the mapped length of the room should be in the
same unit of measure. (If actual room length is in feet then multiply by 12 because
there are 12 inches in a foot!)
3. Divide the actual length of the room by the mapped length. This becomes a ratio or
scale. There are no units of measure. The inches cancel each other out.
4. Now you use the ratio from #3 to determine the mapped size of the other length of
the room, the desks, and the doors. Don’t forget to change your units of measure to be
the same each time.
Actual length of room ______________ if in feet then multiply by 12 to get inches because that is
probably what your mapped length of room will be in. If you are drawing it in cm, then find
that conversion rate and multiply.
