Perimeter : Trim Paint Estimation
Activity Description
Students will analyze the floor plan of a house, measure the size of each room, and calculate the perimeter of the room's walls to paint the baseboards. The worksheet is a good activity to see how the Measurement & Geometry they have learned is used in real life.
Storyline :
Students' applications for the "Precision Painting Estimator" job have been accepted, but to prove their abilities the company has given them a new task. The task is to calculate the paint needed for all the wall baseboards, doors, and door trims. The company has provided a map of the house to be painted.
Students will use the gridlines to measure the length and width of each room and use these values to find the perimeter of the room. The perimeter is the total wall length to be painted.
The next task is to find the perimeter of the doors and the area of the doors as they also need to be painted.
If the baseboard height is 0.25 feet, students will calculate the total trim area, then add it to the door area to find the whole area to be painted.
If one gallon can paint 400 square feet, they will find the total paint required for this activity.
The activity is completely auto-scored.
Learning Objective
The worksheet is a real life application of measurement, perimeter calculation and area calculation. Students can easily relate what they learned in classrooms to a real life scenario.
