Design A Flower Garden Using
Percentages
 Depending on
your students, you may want to introduce this as a whole
class activity and then have students work in pairs.
The following
are questions for students to answer based on the worksheet.
Be sure to record their answers on the board.
1. Describe
the quantities of flowers in the garden?
2. Of the flowers
in your garden, which flower covers the greatest area?
3. What two
flowers combined cover the same area as the Blanketflower?
4. Are there
any combinations of flowers that would cover half of
the garden?
Ask the students
why they are all still getting the same answers even
though their gardens look very different.
Now have students
pair up and place their squares next to each other to
make a larger garden. Ask the same questions. Record
the answers on the board. Ask the students why they
are all still getting the same answers even though they
have doubled the size of the garden.
5. Describe
the quantities of flowers in the garden?
6. Of the flowers
in your garden, which flower covers the greatest area?
7. What two
flowers combined cover the same area as the Blanketflower?
8. Are there
any combinations of flowers that would cover half of
the garden?
Compare answers
between groups. Ask the students why they are all still
getting the same answers even though their gardens are
larger and look even more different.
Now put all
of the students’ squares together into a whole class
garden. Ask the following questions.
9. How many
of the little gardens does the class have?
10. How many
of the little blocks does the class have?
11. What portion
of our whole class garden is yellow (Black-eyed Susans)?
12. What portion
of our whole class garden is blue (Blue Flax)?
13. What portion
of our whole class garden is red (Blanketflowers)?
14. What portion
of our whole class garden is purple (Purple Cone Flowers)?
15. What portion
of our whole class garden is white (Shasta Daisies)?
