Gather your students and ask groups to share their ideas. Tell them that you don’t have enough squares for that and ask them to problem solve how they might determine the number of squares needed without actually doing it. After your introduction to area, some groups might decide that unit squares would need to be placed all over the floor of the classroom. Have them discuss how they could figure out the area of your classroom floor. If not, you may want to take your class to a room or area of your building that is.)ĭivide students into problem solving groups. Be sure to have enough squares to measure the entire length of the longest wall of the room students will measure.Īlso, this initial lesson will work best if your classroom is the shape of a square or rectangle. You might want to laminate these for durability so that you can use them again and again.

You work it out.Aligned Standard: Grade 4 Measurement - 4.MD.3 The unit is square meter because it covers space taken both by length and breadth. So, we have to take only one side of each type. The area of a rectangle is calculated by multiplying length and breadth. The unit will be the same as the unit of length given. For calculating the perimeter, you can just add all the sides together. Since it is a rectangle, you know that the opposite sides are off the equal length, so, there are two sides of length 150 m and two sides of length 400 m. You have to determine its perimeter and area. Lets apply this to a local park, the park is a big rectangle. To understand areas and perimeter, let’s play a game. The area is space of land, which the football court is covering. The area is the space covered by the shape within a perimeter. It is calculated by adding each side’s fencing length. For example, the length of the fence around a football court is called the perimeter. Perimeter is the total distance which is covered around any shape. Now, we will list down the differences between the area and the perimeter of a shape. When you learn areas and perimeters, you end up pulling your hair because they both look like the same thing but really are two completely different things. What is the difference between Area and Perimeter? These worksheets and lessons help students learn how to tackle word problems that involve finding area and perimeter.
