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.

Common Core: MATH

Measurement & Data

Apply the area and perimeter formulas for rectangles in real world and mathematical problems. *For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor*.

Geometry

Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., *x*-axis and *x*-coordinate, *y*-axis and* y*-coordinate).

Geometry

Represent real world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation.

Geometry

Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.

Geometry

Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
