In the second lesson in a multi-part unit, students continue to explore geometric concepts by modeling on the geoboard. After assessing prior knowledge, the teacher engages students in a discussion about common properties among the figures they create. Then, students work in pairs to create four-sided figures and compare them. After completing a series of activities, students discuss what they learned in the lesson. Illuminations provides links to materials and detailed instructions necessary for completing the lesson.

Students will:

  • Use geometric vocabulary.
  • Identify, compare, and analyze characteristics of geometric shapes.
  • Explore parallel, perpendicular, and intersecting lines.

NCTM Standards and Expectations:

  • Describe location and movement using common language and geometric vocabulary.
  • Build and draw geometric objects.
  • Create and describe mental images of objects, patterns, and paths.
  • Recognize geometric ideas and relationships and apply them to other disciplines and to problems that arise in the classroom or in everyday life.

Grade 3

  • Goal 3: Geometry - The learner will recognize and use basic geometric properties of two- and three-dimensional figures.
    • Objective 3.01: Use appropriate vocabulary to compare, describe, and classify two- and three-dimensional figures.
    • Objective 3.02: Use a rectangular coordinate system to solve problems.
      • Graph and identify points with whole number and/or letter coordinates.
      • Describe the path between given points on the plane.

Grade 4

  • Goal 3: Geometry - The learner will recognize and use geometric properties and relationships.
    • Objective 3.01: Use the coordinate system to describe the location and relative position of points and draw figures in the first quadrant.
    • Objective 3.02: Describe the relative position of lines using concepts of parallelism and perpendicularity.
