A 60-minute lesson in which students will review the concept of area.
This lesson plan includes the following resources:
This lesson contains a link to an external video. Please watch the video prior to presenting this lesson to ensure that the content is appropriate for your students.
Review the concept of area and how square units are used to measure it. Revisit the Measuring Area Using Squares video on YouTube. Discuss instances where objects’ areas were measured with squares in class.
Explain to the students that, during this lesson, they will be completing a number of activities to review area. Describe each of the activities listed below. Allow the students to ask questions and/or seek clarification where necessary.
Use the Geoboards on the Math Learning Center website to make shapes and count the squares inside, or make shapes of particular areas.
Using grid paper and two dice, roll the dice and find the sum. Then draw a shape with that number of squares as its area.
Find an object from around the classroom and trace its outline on a piece of grid paper. Shade in and count all the complete squares inside the outline to find the object’s area.
Create ‘creatures’ by making body parts with the following area dimensions: head (9 squares), body (12 squares), arms (3 squares each), legs (3 squares each), ears (1 square each). The creatures can be drawn on grid paper or made using informal square units e.g. sticky notes.
Measure the area of a shape or a small, flat object using circles e.g. counters, coins of same size. Then, repeat the measurement using squares e.g. tiles, 1-in or centimeter cubes. Note the measurements for each, then decide which shape is better for measuring area and why.
Monitor and support the students as they complete the activities. These can be completed as whole class exercises or as small group rotations (mixed ability groups are recommended). Each task should take approximately 10 minutes to complete.
Gather the class together and invite the students to share their experiences of the activities. Review the definition of area and check for any misconceptions.
Encourage more capable students to assist less confident peers during group work.
Allow less confident students to be supported by more capable peers during group work.
