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

Run the same three questions on every shape: how many sides, are any of them equal, are the corners square. If your child insists a square cannot be a rectangle, read the rectangle checklist out loud (four sides, four square corners) and let the square pass every test. Sorting a few paper cutouts into overlapping piles makes the shared names feel normal instead of like a trick.

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 names do the third grade sheets use?
Quadrilateral, rhombus, rectangle, and square: the 3.G.A.1 set. Each problem shows one drawn shape and three of those names, and your child circles the name that fits best.
Why do some shapes seem to have two right answers?
Because they genuinely do. A square is also a rectangle and a rhombus. The sheet asks for the most specific name, which is exactly the reasoning the standard is after.
