A trapezoid is a shape with four sides, and two of those sides run side by side without ever meeting. This 3rd grade identifying trapezoids worksheet starts with a box that gives the rule. It says that a trapezoid is a quadrilateral with exactly one pair of parallel sides. Below the box, there are five shapes, labelled a to e. Some look like tables or roofs, one is a tilted square and one has five sides like a house. Next to each shape, your child checks Yes or No. The page sits on light grid paper, so the straight lines are easy to follow. Page two is the answer key, and it gives a short reason for every answer.
