Key Concepts

  • A rectangle has four sides.
  • A rectangle has four angles (corners).
  • Two sides of a rectangle are longer than the other two sides.

Learning Objectives

  • Students will be able to identify rectangles from other shapes.
  • Students will be able to describe the attributes of a rectangle (four sides, four angles).
  • Students will be able to find rectangles in their environment.

Educator Instructions

  • Introduction (5 mins)
    Begin by reviewing shapes previously learned (circles, squares, triangles). Ask students to recall their attributes. Introduce the concept of a shape hunt. Announce that today's hunt is for rectangles.
  • Defining Rectangles (5 mins)
    Watch the video (or a segment of it). Pause the video at key points to reinforce the definition of a rectangle: four sides, four angles, and two longer sides. Draw a rectangle on the board and label its sides and angles.
  • Classroom Shape Hunt (10 mins)
    Lead a shape hunt in the classroom. Encourage students to point out objects that are rectangles. Discuss why these objects are rectangles (counting sides and angles).
  • Independent Shape Hunt (10 mins)
    Have students independently look for rectangles in the classroom or provide them with pictures to analyze. Students can draw the rectangles they find or list them.
  • Wrap-up (5 mins)
    Review the key attributes of a rectangle. Ask students to share their findings from their shape hunt. Emphasize that rectangles are everywhere!

Interactive Exercises

  • Rectangle Sort
    Provide students with a collection of different shapes (rectangles, squares, triangles, circles). Have them sort the shapes into groups, identifying the rectangles.
  • Drawing Rectangles
    Have students draw their own rectangles. Encourage them to use rulers to make straight lines.

Discussion Questions

  • What makes a rectangle different from a square?
  • Can you think of any real-world objects that are rectangles?
  • Why is it important to know about different shapes?

Skills Developed

  • Shape recognition
  • Observational skills
  • Critical thinking

Educational Standards

CCSS.Math.Content.1.G.A.1:Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes. CCSS.Math.Content.1.G.A.2:Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape. (Students do not need to learn formal names such as 'right rectangular prism.')
