Six shapes, six chances to practice adding side lengths: this perimeter of polygons worksheet moves through rectangles, squares, triangles, pentagons, parallelograms, and hexagons in one sitting.
Each of the six problems on this perimeter of polygons worksheet shows a labeled polygon with all side lengths written in, followed by a show-your-work space and a fill-in-the-blank answer line with the correct unit. Problems use centimeters, meters, and feet, so your student reads units carefully alongside doing the addition. This sheet suits grades 3 through 5 and works well as a first independent practice after you introduce the perimeter formula shown at the top: P = s1 + s2 + s3 and so on.
The formula box and directions are printed right on the sheet, which means your homeschooler can work through it without a separate reference card in front of them. Shapes range from a four-sided rectangle and square to a five-sided pentagon and six-sided hexagon, giving a natural progression in number of sides to add. Students practice reading labeled diagrams, summing unlike-length sides, and recording answers with units, three skills that carry directly into geometry unit studies at the upper elementary level.


A pencil is the right choice here since each problem includes a dedicated show-your-work area where students write out their addition. The labeled diagrams are clear enough for independent practice, though sitting nearby the first time through lets you catch any skipped sides before a habit forms.

Card stock is not needed. Standard copy paper handles the pencil work well. Portrait orientation is set, and printing two copies at once gives your student a fresh sheet for a second timed round later in the week.
