Pentagons Worksheet

A pentagon is a closed shape with five straight sides and five corners, and learning to pick one out of a row of look-alike polygons is a real second grade geometry skill. Students who can already name a square and a triangle often stall on a pentagon, because the only way to be sure is to stop and count the sides. This pentagons worksheet puts that counting habit at the center of the lesson, asking students to look past size, color and tilt and judge every shape by its sides alone.

The sheet opens with eight shapes printed in identical boxes. Four of them are pentagons, drawn at different sizes, turned to different angles and shaded in different tints, so a student cannot guess the answer from how a shape looks or where it sits on the page. The distractors are a square, a triangle and two hexagons, which sit on either side of five sides and force a genuine count. A second section hands the page back to the student with a large open box and a simple instruction: draw two pentagons of your own. Print this pentagons worksheet for morning work, a geometry center, a quick check before a unit test, or homework that a family can help with in five minutes.

What’s Included

• One printable page with eight polygons to identify and circle
• Four pentagons mixed with a square, a triangle and two hexagons
• A large open box for drawing two original pentagons
• A complete answer key showing every pentagon circled
• Clear, single-step directions written at a second grade reading level

Three Reasons This Helps Kids

• It builds a habit of counting. Because size, color and rotation are deliberately scrambled, the only reliable route to the answer is counting the sides, which is exactly the strategy the standard asks for.
• It separates the shape from its picture. One pentagon is upside down and another is tipped on its side, so students learn that turning a shape never changes what it is.
• It moves from recognizing to making. Drawing a pentagon from scratch is a harder task than spotting one, and it shows a teacher immediately who has truly understood five sides.

Teacher and Parent Ideas

Before students pick up a pencil, hold up the page and count the sides of one shape together out loud, tapping each side as you go. Ask students to say the side count under their breath for every shape, then compare with a partner and explain any disagreement. Once the page is finished, send students on a short pentagon hunt around the room or the house and have them sketch what they find in the margin. If you are building a longer unit, this 2nd grade shapes worksheet pairs naturally with hexagon and quadrilateral practice, and the drawing box can be repeated on blank paper for extra repetitions.
