Triangles word search, scramble and crossword puzzle

Triangles word search, scramble and crossword puzzle

I made this triangles puzzle set for my 4th graders during our geometry unit. The kids could point to a triangle but had no idea there were different types based on sides or angles. So I put together a word search, a word scramble, and a crossword using words like triangle, side, angle, vertex, equilateral, isosceles, scalene, acute triangle, right triangle, obtuse triangle, congruent, equal, sum, 180 degrees, and polygon. Nothing fancy — just puzzles to help the triangle vocabulary finally stick.

The PDF is four pages. Three puzzles plus one answer key page. The word search works well for quiet time after recess. The scramble gets them talking because they argue about whether an equilateral triangle can also be a right triangle. The crossword I use for partners with picture clues. I added a couple simple triangle drawings with labeled sides and angles but nothing too busy.

Works for 4th through 5th grade. Print and go. Sometimes I have early finishers name the three types of triangles by sides on the back. The kids actually ask for these now.
