5. Question 1
Ms. Morgan wants to make a garden, outside of her house. The state said that she has 1000 ft to make a garden, she wants a 200 ft squared garden. Should she use a meter stick or a yard stick, justify your answer.

6. Answer to Question 1
She should use a yard stick, because a yard stick is the same as three feet. She should not use a meter stick, because she would have to convert centimeters into inches, and then inches into feet.

7. Question 2
Ms. Morgan's neighbor, Iceysis wanted to measure a lacrosse field, he thinks it is as long as a football field. If it is, then how long could it be? What units and tools should Iceysis use to measure?

8. Answer to question 2
If it is as long as a football field then it is 100 yards long, so Iceysis should use yards or meters to measure it. He would do this with a yard or meter stick. A yard stick would be the best, but he could use a meter stick. He would then have to do conversions of be happy with an estimate!
