Digital Perimeter Examples for 3rd Grade

Teachers! Don’t reach for another perimeter worksheet! While worksheets certainly have a place and serve a purpose in the classroom, why not vary your lesson delivery with an engaging digital resource? This interactive activity is chock-full of perimeter questions that are sure to keep your students on-task for the duration of your math lesson!

This ocean-themed interactive activity contains a variety of perimeter questions for students to practice calculating the perimeter of composite shapes. There are nine slides to work through, each containing a wide variety of perimeter examples for students to engage with. Some of the activities include:

• Drag the coral over the fish displaying the correct perimeter.
• Drag the coral over the fish displaying the correct missing side length.
• Drag the fish over the shape with the perimeter that matches the number in the pearl.
• Use the perimeters to color the mystery picture.
• Use the perimeters to color a path through the maze.
• Match the correct perimeter to its shape.
• Match the correct shape to its missing side length.

This resource downloads as an editable Google Slides file. A printable PDF containing the answers is also available via a separate dropdown.

This resource makes a great revision activity once your students have already had some experience finding the perimeter of composite shapes. Use it as a warm-up at the beginning of your math lesson, or as a review lesson at the end to see how well your students are able to answer the perimeter questions.
