Your students have learned about basic shapes in kindergarten, and now it’s time to establish the “rules” that go with attributes and allow students to think in their own way and come up with ideas.

See the fact file below for more information on the Distinguishing Defining Attributes or alternatively, you can download our 27-page Geometry: Distinguishing Defining Attributes CCSS 1.G.1 worksheet pack to utilise within the classroom or home environment.

Key Facts & Information

LEARNING OBJECTIVE:

  • At the end of the lesson, students will be able to 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. They will be able to identify common attributes of a group of shapes and describe, compare, and name 2-D shapes.

A NOTE FOR THE TEACHER:

  • When teaching distinguishing attributes, try the following:
    • It’s important for students to be able to think through their ideas. They don’t have to be correct immediately, but they need to be able to reason and then adjust.
    • The big idea for this lesson is to prove it!
    • Facilitate with questions rather than giving answers, e.g., What shape is this? How are you sure that is the shape? What sentence could I write to prove it? How are you sure this is a rectangle, not a square?

THEORY:

  • Your students have learned about basic shapes in kindergarten, and now it’s time to establish the “rules” that go with attributes and allow students to think in their own way and come up with ideas.
  • Through guidance with the rules, they will then be able to adjust their ideas until they reach a correct answer.

CAN YOU FIGURE OUT THE RULE?

  • Look at the shapes in the circle. They’re all different shapes, but what do they all have in common? Why do you think the shapes outside the circle can’t go in?

  • Answer: The rule is that only shapes with straight sides can go in the circle. The shapes outside of the circle have curved lines.
