About these quadrilaterals worksheets

A quadrilateral is any closed shape with 4 straight sides. In 3rd grade children learn that squares, rectangles and rhombuses are all quadrilaterals, and that a square is also a rectangle and a rhombus because it has 4 right angles and 4 equal sides.

These worksheets use simple marks that children learn to read: a small square in a corner shows a right angle, and little marks on sides show they are equal. Children decide whether shapes are quadrilaterals, circle every name that fits, fill in an attributes table, sort shapes into a rectangles and rhombuses diagram, and draw their own quadrilaterals on dot paper.

Every shape's marks are worked out from its exact geometry, so a mark always tells the truth. Practice pages have an answer key on page 2.

Standards

  • CCSS.MATH.CONTENT.3.G.A.1Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.

How to use them

  1. Start with the Quadrilaterals Chart and the marks for right angles and equal sides.
  2. Use Quadrilateral or Not? to fix the definition: closed, 4 straight sides.
  3. Name the Quadrilateral Sheet A shows upright shapes; Sheet B turns them.
  4. Use the attributes table and the sorting diagram to show that a square belongs to both rectangles and rhombuses.
  5. Finish with Draw Quadrilaterals and Shape Riddles.

Teaching tips

  • A turned square is still a square. Children often call it a diamond; ask them to check the sides and corners.
  • Use the corner of a sheet of paper to test for right angles.
  • Say 'every square is a rectangle, but not every rectangle is a square.'
  • Draw a quadrilateral that is none of the special kinds: it shows children the big category.

Questions teachers and parents ask

What is a quadrilateral?

Any closed flat shape with 4 straight sides and 4 angles. Squares, rectangles, rhombuses, trapezoids, parallelograms and kites are all quadrilaterals.

Is a square a rectangle?

Yes. A rectangle has 4 right angles, and a square does too. A square is also a rhombus because all 4 sides are equal.

What quadrilaterals do 3rd graders need to know?

Rhombuses, rectangles and squares, and quadrilaterals that are none of these. Many classes also name trapezoids, parallelograms and kites.
