Title: What's Missing?
Description:

In this activity, students will practice finding the perimeter of rectangles and rectilinear shapes that have missing lengths. This activity includes a set of 18 task cards and a recording sheet.

Subject: Mathematics (3)
Title: Racing Around
Description:

This activity is a Google slideshow that includes a read-aloud of the book, Racing Around, by Stuart Murphy. Racing Around is a story to help students understand perimeter. While the story is being read, the students will watch as the character in the book has to determine the perimeter of the athletic field, zoo, and finally, Perimeter Path. After the story has been read, the students will be asked essential questions from the story.

Subject: Mathematics (3)
Title: My New Bedroom
Description:

In this activity, students will solve a real-world problem involving perimeter. The task asks students to find the perimeter of their new bedroom. A diagram of the room is given, but students must determine the length of the missing sides to correctly calculate the perimeter.

Subject: Mathematics (3)
Title: Perimeters of Pools
Description:

During this learning activity, students will solve a real-life task that allows students to find the perimeter of several pools (polygons). Students will write equations and solve them to find the perimeter of several polygons.

Subject: Mathematics (3)
Title: Perimeter Introduction Activity
Description:

This is an introductory activity for teaching perimeter. First, students will watch a perimeter song video. Then, they will work with manipulatives to build a garden (array) and discuss what the measurement would be if a ladybug walked around the edge of the garden. This gives the students an opportunity to explore the perimeter using concrete materials.

Subject: Mathematics (3)
Title: Finding the Unknown Side of Safety Signs
Description:

This learning activity allows students to explain their thinking to find the unknown side of a polygon when the perimeter is given. Students will solve three different problems where the perimeter is given and knowledge of polygon attributes are needed to find the missing sides. This activity can be used as an assessment or an extension activity after students have mastered how to find the perimeter of a polygon.
