Title
The Pool
Lesson Objective
This can be an introductory lesson on area and perimeter. Students will use square blocks or tiles to determine Grandpa's pool of 24
square units.
Background Information for Teacher
Students should have a good understanding of multiplication for this task. If they have been taught using arrays/area they will get
this quickly. This is a great beginning task for beginners! Words in bold will be said aloud by the teacher.
Student Prior Knowledge
Students should have an understanding of multiplication.
Materials:
● Centimeter cubes/tiles
● Graph paper
● Pencil/paper
Step 2: Teach Lesson
The student will incorporate what they know about multiplication to determine area. They will also be asked to determine perimeter.
Tell the student, Grandpa is building a swimming pool in his backyard. The pool will be 24 square units with 4 straight sides.
You are asked to help them find different shapes the pool could be.
How many different shapes can you make? Allow the student time to respond.
After the student has found the area they will be responsible to find the perimeter for each shape for fencing.
Write an equation to represent the area and the perimeter for each shape.
Questions to be asked to determine the student's understanding:
What does that mean?
What does your model show?
What tools help you determine what you need to find out?
What have you discovered about area so far?
What challenges are you finding?
Explain what you are doing?
When the student has finished, they can figure out how many tiles would be needed to placed around the pool.
During the discussion have the student defend their solution or look for other ways to solve the problem.
Have the student complete the worksheets below for extra practice.
