The reason my students will complete this lesson is to see that though the area of a shape stays the same, the perimeter still changes. This is a difficult concept for my students to grasp each year. I think that using Kidspiration will be a great way to present this lesson. The square tiles application is perfect because it allows my students to see a visual of the concept in front of them. Students can manipulate the squares on their own, so they are building their own understanding of the concept. Additionally, technology is always a motivating tool for students.
Math; Measurement; Perimeter, Area
Activator: Watch United Streaming video “Rectangle Chart, Area and Perimeter” with students to review the concepts of area and perimeter.
Engage: Students will discuss the concepts of perimeter in terms of something they are familiar with – dining tables to connect to their lives.
Before we begin our math lesson today, I want you to talk with your table buddies about two questions: What shape is your kitchen or your dining room table? How many people can sit there?
Allow students time to talk with their buddies.
What were some of the things your group discussed.
Allow students to share their answers. Talk about possible seating arrangements at differently shaped tables. For example, how does a square table determine how many people can sit there? How does a circle table?
Today we are going to look at the shapes of different tables to figure out how many people can sit there.
Draw a square on the board.
If we pretend this one table, how many people can sit here? Each side will leave room for one person.
Allow students to answer (4 sides, 4 people).
What do you think will happen if I double the area, and make the area of the table 2 square units?
Draw this on the board and wait for student responses.
Today, you are going to find out how many people can sit at different sized tables. You will need to calculate the area and perimeter of each table. Open up your Kidspiration file.
Allow students to open files, and go over the top half of the page together. Introduce the example on the bottom of page 1 with students before they get started on their own.
Explore: Allow students time to complete the Kidspiration activity.
Now that you all have your task, I would like you all to begin working. You have a lot of things to do today, and this should take up all of our math time. If you have a question please raise your hand.
Circulate and help students in need.
Students will save their work to my “handin” folder at school so that I can review their work. Also, students are responsible for turning in an exit card citing three things they learned during the lesson. This way, I can see who has connected the concepts of area and perimeter with the banquet table problem.
Kidspiration software available to each student
