Changing GardensSupposed you are designing a rectangular

flower and vegetable garden.

Do you think we might want to put a fence around our garden?

If so, why would a fence be important to put around your garden?

What materials would you need to make a fence?

Changing GardensYour task is to work with your group to find

different rectangles that have a perimeter of 24 feet, given the following conditions:

• The fence must have no gaps or overlaps• The length of each side of the rectangular

garden must have a whole-number measurement.

Tools• 24 inch piece of string• Colored Tiles

Changing GardensSuppose we have 24 feet of fence to put AROUND

our garden. Therefore, what will the perimeter of our garden be?

24

Before you start constructing your fence, I want you to predict whether or not the area of all the rectangles you create with your 24 feet of fence will be the same or not. Write down your predictions on the top of your paper.

Have each group share one of the rectangles they were able to create.

What discoveries did you make about the relationship between the perimeter of a rectangle and its length and width?Did you need to measure every side of the rectangle to find the perimeter? Why or why not?How does knowing the characteristics of a rectangle help you find its perimeter?If someone gave you the length and width of a rectangle, could you find the perimeter? How?

Instructions for Garden 2Your task is to find different rectangles that

have a perimeter of 30 feet, remember the following conditions:

• The fence must have no gaps or overlaps

• The length of each side of the rectangular garden must have a whole-number measurement
