The kind of problems you'll get

Draw a shape using all the pieces. Do not overlap pieces.

  1. Join two matching squares along one full side.

    Answer: They make a rectangle with no gaps or overlaps.

Most problems on this sheet sit beside a picture, model or diagram, so this is the worked example the sheet itself prints. The answer key on page two prints the answer under every problem.

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 after the problems.

This sheet is one of the versions on the 1st grade identifying 2d shapes page, with its own difficulty choices and its own answer key.

How to teach this

Have your child touch each side while counting before circling. The rhombus and trapezoid are easy to confuse with a square or rectangle at a glance, but the counts and corner shapes settle it. If tilted squares cause trouble, turn the page until the shape looks familiar, then turn it back and ask whether anything about the shape actually changed.

Watch for: Kids call a stretched shape a rectangle only when it lies flat. A rectangle standing on end is still a rectangle; turning a shape never changes its name. Kids think a square stops being a square when it is tilted. A tilted square still has four equal sides and four square corners, so it is still a square.
