Quadrilaterals Chart
Squares, rectangles, rhombuses, parallelograms, trapezoids and other quadrilaterals, with side and corner clues.
Is It a Quadrilateral?
A mix of shapes. Circle every one with 4 straight sides and 4 corners that is closed all the way around.
Name the Quadrilateral
Squares, rectangles, rhombuses, parallelograms and trapezoids, some tilted, to name.
Sort the Shapes
Check every name that fits each shape. A square gets five checks!
Draw on Dot Paper
Draw a quadrilateral that fits each clue, like "a rhombus that is not a square."
Shape Riddles
Riddles about sides and corners, like "I have 4 equal sides but no square corners."

What it is
A quadrilateral is any closed shape with 4 straight sides and 4 corners. Third graders learn the special kinds: squares, rectangles, rhombuses, parallelograms and trapezoids. They also learn that one shape can have more than one name. A square is also a rectangle, a rhombus and a parallelogram.

How to teach it
- Hunt for quadrilaterals around the house, like doors, windows and books.
- Look at the sides first. Are they equal? Do any pairs never meet?
- Then look at the corners. Are they square corners, like the corner of a page?
- Use the corner of a sheet of paper to test for square corners.
- Talk about why a square can be called a rectangle, but a rectangle is not always a square.
Common mistakes
- Thinking a tilted square is a diamond and not a square.
- Thinking a square cannot also be a rectangle.
- Counting a shape with a curved side or a gap as a quadrilateral.
