Making a room map

1) Measure the room

• Make sure that you use consistent units (preferably centimeters)
• Measure the walls, doors, windows, etc.
• Measure the pieces of furniture that you will include on your map

2) Make a scale

• Sketch the longest wall. Write the measured length (real size) next to it
• Measure the wall on the map (find the map size)
• Make sure you're using the same units: cm, m, inches, etc.!!!
• Divide the real size by the map size
• The scale is your answer.
• 1 unit of map measure = "answer" units of real world
• Example:
•  real size = 860 cm, map size = 20 cm. 
• 860 divided by 20 is 43. 
• The scale is thus 1 cm = 43 cm

3) Figure out the map size of everything else

• Divide the real size by the scale
• Example:
•  real size = 86 cm
• [map scale is 1 cm =43 cm (from above)]
• 86 divided by 43 is 2. 
• Thus the object should be 2 cm on the map
• Do this for all objects in the room

4) Draw in the rest of the map

5) Make sure to include everything required on the grading scale
