Support your students' comprehension of perimeter word problems by teaching them to use an engaging strategy and graphic organizer. This lesson can stand alone or be used as a pre-lesson for *Polygon Perimeters with Tantalizing Tangrams!*
Students will be able to find the perimeter of various polygons by adding the sides or measuring with a ruler.
Students will be able to analyze the meaning of perimeter word problems and make a plan to solve them using a graphic organizer.
Give each student an index card and have them write their name on it and write the number one in the top left corner. Tell them that they are going to demonstrate their understanding of a concept by drawing a picture.
Write the word perimeter on the board and instruct learners to draw a definition of perimeter without using words. Allow them to use numbers to support their visual explanation.
Instruct students to turn and talk about their drawing with a partner and listen to student conversations to check for understanding. Call on nonvolunteers to share what they talked about with their partner.
Collect the index cards. They will be passed out to students at the end of the lesson.
Tell the class that they will be solving perimeter word problems today using a strategy and a graphic organizer to help them make sure they understand what the word problem is asking.
