This 4th grade geometry crossword covers eight vocabulary terms from the Common Core Geometry strand: acute, angle, line, obtuse, parallel, point, ray, and right. Students match each definition clue to a term from the word bank and write it into the numbered grid. The clues rest on exact definitions, so RAY only fits once a student knows a ray starts at one endpoint and travels in a single direction. A completed answer grid sits at the back for marking.
4.G.1
“Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.”
Every clue defines a term named in this standard. Students identify acute, obtuse, and right angles, parallel lines, points, lines, and rays from their definitions across clues 1 to 7.
The word bank lists all eight answers in capitals: ACUTE, ANGLE, LINE, OBTUSE, PARALLEL, POINT, RAY, and RIGHT. The numbered grid interlocks them, with PARALLEL running eight squares along the bottom row.
Three Across clues and five Down clues define each term by its properties. 4 Across asks for lines that run side by side, stay the exact same distance apart, and never intersect. 6 Down wants a straight path of points that continues forever in both opposite directions.
The last page prints the solutions for both directions and the filled grid, so ACUTE, PARALLEL, ANGLE, OBTUSE, RAY, POINT, RIGHT, and LINE can be checked at a glance.
Vocabulary warm-up
Open a lines and angles unit with it. The word bank keeps the puzzle within reach before students have the definitions cold.
Fast finishers
Keep a small stack for students who finish early. The puzzle stands alone, and the answers page makes self-checking easy.
Pre-quiz review
Fold the word bank under before copying for students who need a stretch. Writing PARALLEL from its definition alone is a fair test of the term.
