Room Mapping

Measure and design! Determine the perimeter of a space and create a map of your favorite room.

  • Grade 3
    Grade 4
  • 30 to 60 minutes
  • Directions

    1. Ask students to identify their favorite rooms in a house or other structure. If you prefer, the selection can be restricted to rooms in the school.
    2. Instruct students to measure the perimeter of their selected rooms.
    3. Give each student a piece of large white paper, Crayola® Classic Crayons, and a ruler. Ask students to draw the perimeter of their rooms using a scale of 1 inch (2.54 cm) equal to 1 foot (30.48 cm). Therefore, a room with a perimeter of 14’ by 8’ (4.27m by 2.44m) would be 14” by 8” (35.56cm by 20.32cm).
    4. Instruct the students to write the perimeter lengths on the drawing.
    5. Ask the students to draw the furniture, windows, and doors as close to scale as possible based on the size of their rooms.
    6. Remind students to create a legend of objects in their rooms.
    7. Once a student’s work is complete, ask him to find a partner and pose these questions: Approximately what percentage of the room is filled with objects? Can you find a way to organize the objects to create more space? Encourage students to discuss the possibilities!
  • Standards

    LA: Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade 4 topics and texts, building on others’ ideas and expressing their own clearly.

    MATH: Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.

    MATH: Solve problems involving measurement and conversions of measurements from a larger unit to a smaller unit.

    MATH: Apply the area and perimeter formulas for rectangles in real world and mathematical problems.

    VA: Work individually and collaboratively to create two- and three-dimensional works of art that make cohesive visual statements and that employ the elements of art and principles of design.

  • Adaptations

    Advanced students could be assigned to measure the perimeter of the furniture to accurately define the area of the objects in the room.

    Use Crayola® Classic Markers instead of crayons.

    Encourage students to investigate the topic of Interior Design or Architecture.

    Make this a competition in your classroom. Instead of giving choice of room, have all the students use your classroom space. Make it a two step process: document what is currently in the room and then re-design the room to create more functional space. The prize: the winning re-design will be the classroom set up for a month and a bulletin board will display their process!
