With that said, I have discovered that my college students hate learning, reviewing or even practicing math vocabulary. I always begin the semester with a Mathematical Language Activity (see below) in which the students write two paragraphs about how they feel about the math language. You'd be surprised at how much I learn!
Often, I create two different puzzles for the same math vocabulary. The first puzzle is easier as it contains a word bank while the second puzzle does not. Since both puzzles are laid out differently, I can use one as a review and the second one as a homework assignment or maybe even as a quiz.
My newest one is on circles. Both puzzles feature 18 terms associated with circles. The words showcased in both puzzles are arc, area, chord, circle, circumference, degrees, diameter, equidistant, perimeter, pi, radii, radius, secant, semicircle, tangent and two.
Also available are crosswords on polygons (includes 16 geometric shapes with an emphasis on quadrilaterals and triangles), plain geometry (features 25 different geometry terms with an emphasis on points, lines, and angles), and solid geometry (emphasizes polyhedrons, circles, and formulas for area, surface area, and volume).
To keep my old gray matter working, I do the paper crossword every Sunday. To many of our students, math is like a puzzle, but maybe they can learn to love figuring out the puzzle by doing these crosswords. Why not give one a try in your classroom?
