What is on this worksheet

Students count the sides of triangles, squares, rectangles, pentagons and hexagons and write the number in one box.

• Students count: Sides only

You can change any of these settings above. Press "New problems" for a fresh set with the same settings, or pick Version A to Z to print different sheets for neighboring desks. The answer key always matches.

About sides and vertices worksheets

Each row shows a shape and two answer boxes, one for the number of sides and one for the number of vertices. The shapes are drawn in different proportions and turns, so students count what is there instead of remembering a picture.

Choose five basic shapes or nine (with the parallelogram, trapezoid, kite and octagon), print the shape names or leave them off, and ask for sides, vertices or both. Because every shape here is a closed polygon, the number of sides always equals the number of vertices, which makes a good thing to notice.

Printing

US Letter or A4, portrait: choose your paper size above. Print at 100 percent (actual size). Use "Black and white" for the copier, or "Color" for display pages and mini books.
