Shapes and Play

10 min

Narrative

The purpose of this Warm-up is to elicit the idea that different shapes are used in the design of park areas, which will be useful when students design a park in a later activity. While students may notice and wonder many things about these images, how different shapes are used in the design of the park is the important discussion point.

Launch

  • Groups of 2
  • Display the image.
  • “What do you notice? What do you wonder?”
  • 1 minute: quiet think time
Teacher Instructions
  • “Discuss your thinking with your partner.”
  • 1 minute: partner discussion
  • Share and record responses.

Student Task

What do you notice? What do you wonder?

Sample Response

Students may notice:
  • These both look like the same park, but one is a photograph and one is a map.
  • The map doesn’t have as much detail as the photograph.
  • The park is shaped like a rectangle.
  • The park is surrounded by buildings.
  • The park has 2 lakes and some buildings.
  • There’s a circular area in the middle that’s been partitioned into 4 parts.
  • There are paths that go through the park and split up different areas.
  • The shapes in the park have rounded sides.
Students may wonder:
  • What do the letters stand for on the map?
  • How many trees are in the park?
  • What are the buildings in the park used for?
  • Where is this park located?
  • Is there a playground in the park?
  • How much space does the park take up?
Activity Synthesis (Teacher Notes)
  • “How would it change the look of the park if you could only use quadrilaterals to design it?” (It would be more boxy. There might be some rectangles and rhombuses. You could make it look kind of like it does now, but you wouldn't have any curved lines.)
