Angles and Lines Word Search, Scramble and Crossword Puzzle

I made this angles and lines puzzle set for my Grade 3 and 4 students during our geometry unit. The kids could draw a line but had no idea what words like parallel, perpendicular, acute, or obtuse meant. So I put together a word search, a word scramble, and a crossword using words like parallel, perpendicular, right angle, acute angle, obtuse angle, and straight angle. Nothing fancy — just puzzles to help the angle and line terms finally stick.

The PDFs are six pages. Three puzzles, each with its own answer page. The word search works well for quiet time after recess. The scramble gets them talking because they argue about whether parallel lines ever meet. The crossword I use for partners. I added a couple simple line and angle drawings but nothing too busy.

Works for Grades 3–5. Print and go. Sometimes I have early finishers draw an acute angle and an obtuse angle on the back. The kids actually ask for these now.
