Design a Playroom
Lesson Objective
Students will design a playroom the shape of a polygon. Different attributes are worth different amounts of money. Students want to
design the shape that will make them the most money.
Background Information for Teacher
Attributes of shapes should already be taught before assigning this task. Students should be able to determine parallel lines, and
know the 3 types of angles. Vocabulary such as: quadrilateral and parallelogram should also be familiar. Words in bold are said by
the teacher.
Student Prior Knowledge
Students should have already had a lesson on polygon attributes. They will use what they know about attributes to design a playroom
that will earn them the most money.

Step-by-Step Guided Lesson
Step 1: Start Video
(Tips: Interact with the video by pausing, to ask questions or discuss information viewed with student.)
Step 2: Teach Lesson
In this task, the student will be asked to be a designer of a playroom. They will be paid for certain attributes in the playroom.
The student will understand the shapes in different categories - rhombi, rectangles and others - share attributes and that the shared
attributes can define a larger category - quadrilaterals.
Before the task ask the student, "What kind of things would be in a playroom? What shapes might they take up? Today you
will use what you know about playing in a game room to design your own game room, but it must meet criteria for you to be
Design a playroom the shape of a polygon. Each polygon has attributes. Different attributes are worth different amounts of money. As
the designer, you will get money for certain attributes.
Attributes are worth the following amounts:
Right angles - $10 each - color blue.
Greater than a right angle - $7 each - color red
Less than a right angle - $15 each - color orange
Parallel lines - $20 set - color green
Quadrilaterals - $25 - color purple
Other polygons- $12 - color brown
Let the student figure out what kind of shapes would get them the greatest amount of money for their work. Once they have
determined the shape they will make their game room - they will need to determine the games available inside the room and how
much space (shapes) that the games will need.
Questions that might be asked to help the student:
What would be the shape of the room?
What have you discovered about the shapes?
Is there another way you can do that?
How do you know?
What choices do you have?
How do you know?
How are the shapes similar or different?
Explain why you chose those shapes?
After the students have chosen and drawn their shape on the student page, have them determine the kind of games they will have in
their game-room and what shapes the game areas will take up.
The student will need to draw the shapes inside the game room and label the games that will be available. The student will share a
their creations. This is NOT a show and tell. The teacher needs to ask questions for clarification to determine understanding.
Make sure to make connections between attributes of the different shapes.
