1.G.1 – There’s no shape like home.

1.G.1 Defining Shape Attributes

If I only had a brain… I’d use it to identify and describe shapes!

This 1-page worksheet includes 6 multiple-choice questions aligned to Common Core 1.G.1. It quizzes first graders on distinguishing attributes of shapes (like number of sides and vertices) from non-defining attributes. An answer key is included for quick and easy checking—no trip down the Yellow Brick Road required.


1.G.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.
