Description
This Drawing Non-Quadrilaterals Worksheet helps 3rd grade students understand that a quadrilateral is any shape with four straight sides and four angles, and that every other polygon belongs to a different family. Students use attributes such as the number of sides, the number of vertices, and the number of square corners to draw and name triangles, pentagons, hexagons, and octagons.
The drawing non-quadrilaterals worksheet gives students six rule cards. Each card states how many sides a shape has and how many square corners it needs. Students connect the dots on a dot grid to draw a shape that follows the rule, then write the name of the shape on the line. A final question asks students to decide whether a four-sided shape with no square corners is still a quadrilateral and to explain how they know. This 3rd grade geometry worksheet works well as guided practice, independent work, or a quick check after a lesson on polygons.
What’s Included
- One worksheet page with six dot-grid drawing cards and one written explanation question
- An answer key page with a sample drawing for every rule (student drawings may vary) and the correct shape names
Why This Worksheet Helps Kids
First, drawing a shape from a rule makes students think about attributes instead of just recognizing a picture. Second, the dot grid gives children straight, accurate sides and clear vertices, so they can count sides and spot square corners with confidence. Third, the explanation question builds math vocabulary and asks students to justify their thinking, which is an important skill on geometry tests.
Ideas for Teachers and Parents
Have students compare their drawings with a partner, since many different shapes can follow the same rule. Ask them to point to each square corner and count the vertices out loud. As an extension, challenge students to draw a second shape for each card that also follows the rule, or to write their own rule for a classmate to solve.
