Design A Flower Garden Using Percentages

Tending the garden.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.

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 studentsí squares together into a whole class garden. Ask the following questions.

9. How many of the little gardens does the class have?
