About this worksheet

A geometry vocabulary crossword for 3rd grade using seven terms from the quadrilaterals unit: polygon, quadrilateral, rectangle, rhombus, side, square, and vertex. Each clue is a definition with a letter count, from "a corner point where two sides of a shape meet (6 letters)" to the 13-letter quadrilateral itself spanning the grid. The word bank is printed above the puzzle, and the answer key includes the completed letter grid alongside row and column positions for every word.

Curriculum objectives covered

3.G.1

“Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.”

The four Down clues are the standard's category definitions in disguise; distinguishing the rhombus clue from the square clue requires knowing which attribute each shape may drop.

What's inside this worksheet

Word bank and grid

Seven terms sit in a box above a 10-row crossword grid with numbered starting squares. QUADRILATERAL runs the full 13 columns of row 2.

Across clues

Three definitions to place: a straight line segment of a polygon (SIDE), any closed polygon with exactly four sides and four angles (QUADRILATERAL), and a corner point where two sides meet (VERTEX).

Down clues

Four more: a closed flat 2D shape with straight sides (POLYGON), a quadrilateral with four equal sides and four right angles (SQUARE), one with four right angles and opposite sides equal (RECTANGLE), and one with four equal sides but not necessarily right angles (RHOMBUS).

How teachers use it

Vocabulary consolidation

Offer it late in the unit rather than early. The rhombus and square clues differ by one phrase, not necessarily right angles, and only students who own the definitions notice.

Early-finisher drawer

Keep copies in the fast-finisher tray during the geometry unit. The printed word bank and letter counts make it self-serve; nobody needs to ask you for a hint.

Bank-free rerun

For a second pass, fold the word bank under before copying. Recalling VERTEX from "a corner point" cold is a different task from matching it out of seven candidates.
