What This Standard Means
What Students Need to Do
- Students identify shapes by counting straight sides and corners and noticing curved edges. They draw closed shapes that match a given set of features.
What Mastery Looks Like
- Given a clue such as “four straight sides and four corners,” a student can pick matching shapes and draw one. They can point to the sides and corners that match the clue.
Common Misconceptions
- Students may reject a tilted triangle because it does not point up. They may count an open three-line drawing as a triangle or mistake a curved edge for a straight side.
How to Assess It
- Show a tilted triangle, a square, a circle, and an open three-line figure. Ask students to circle the closed shape with three straight sides, then draw another one.

Ways to Teach It
Give pairs craft sticks and clay dots to build closed shapes with three or four straight sides, then count the corners.
Show an upright triangle and a tilted triangle, and ask students to explain how they know both are triangles.
Play shape bingo with cards showing triangles, squares, rectangles, and circles; call clues such as “three straight sides and three corners.”
Hand out a playground photo and ask students to trace one closed shape and label its straight sides and corners.
