4th grade classifying quadrilaterals worksheets

Fourth grade adds parallelogram and trapezoid to the name choices. Your child checks whether opposite sides run parallel and whether corners are square, then circles the best name. The same figure can earn several.

The kind of problems you'll get

Circle the most specific name or the best answer, or write the count on the line.

  1. Circle the best name for the shape.

    Answer: parallelogram

  2. How many pairs of parallel sides?
  3. Does this shape have a right angle?

Every print pulls a fresh set of problems at this level, so a make-up test or a second sibling never gets the same sheet.

What's on each sheet

Every version prints on US Letter or A4, with its answer key on the last page.

How to teach this

Have your child trace the parallel sides with a finger before circling anything. Parallelogram and trapezoid are decided by that one check. The corner of an index card works as a right-angle tester for rectangles and squares. When two names both fit, ask for the most specific one, then ask why the broader one is still true.

Watch for: Kids decide a square is not a rectangle. It is one, a special rectangle whose four sides happen to be equal. Kids name a tilted square a rhombus and stop there. The name square still applies whatever way the shape sits on the page.

Common questions about classifying quadrilaterals

What is new compared to the third grade sheets?
Parallelogram and trapezoid join the name choices, so your child now checks for parallel sides as well as square corners and equal sides. That is the 4.G.A.2 upgrade.
How does my child tell a parallelogram from a trapezoid?
Count the pairs of parallel sides. Two pairs make a parallelogram; exactly one pair makes a trapezoid on these sheets. Tracing each pair with a finger keeps the check honest.
