Examples, solutions, videos, and songs to help Grade 1 kids learn how 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.

The following diagrams show some shapes for first grade kids. Scroll down the page more examples.

Common Core: 1.G.1

### Learning Targets:

• I can explain the difference between defining attributes (e.g., sides, angles, faces) and non-defining attributes (e.g., color, orientations, overall size).
• I can construct and draw a shape when given defining attributes.
• I can sort shapes (e.g., attribute blocks, polygon figures) by shape, number of sides, size or number of angles
• I can use geoboards, toothpicks, straws, paper and pencil, computer games to build shapes that possess the defining attributes
• I can explain how two shapes are alike or how they are different from each other

Defining Attributes of Shapes - 1.G.1
This level is about identifying shapes and the defining attributes of shapes. It relates to standard 1.G.1 of the common core. Students learn about the difference between closed & open shapes, and the defining attributes of triangles, squares, rectangles & circles. Learn about basic shapes and their attributes (open or closed, number of sides, straight or curved sides)

Build and draw shapes that possess defining attributes.

Hands On with 3D Geometric Shapes
The kids had fun using toothpicks and marshmallows to make 3D shapes.
