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.
