How to do it
- Count the sides and corners.
- Check that every side is straight.
- Check that the shape is closed, then circle it.

About this worksheet
A mix of shapes. Circle every one with 4 straight sides and 4 corners that is closed all the way around.
What kids practice
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.
Watch for
- 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.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full quadrilaterals guide for 3rd grade.
