Students practice finding the perimeter of shapes on this worksheet! Each page starts with two simple shapes, like a rectangle and a square. Each side of the shape is labeled. Students have to add up the sides and finish the prompt "The perimeter is ___."

Then, there are two shapes that are shaded green. These shapes can be simple, like a rectangle, but most of them have many different sides. All sides are labeled with whole numbers, but 5th- and 6th-grade pages have shapes that are labeled with decimal numbers.

All shapes are displayed in a square so students can see each problem clearly. They can be completed as a math minute, or the entire worksheet can be completed during class, as extra credit, or as homework.

Perimeter is a practical skill that's important for students to learn, but it also supports the understanding of measurement and geometry. When they get started learning about perimeter, it's helpful to label the sides and ask students to add them. Young students can add single-digit numbers on simple shapes, like triangles and rectangles. Older students can add decimals on wacky shapes with many sides.

If you have older students who need a challenge, give them the perimeter and ask them to label the sides on a shape so they equal that number. They could also draw their own shape with sides that add up to the given perimeter.
