Read the Headline Story to the students. Encourage your students to create challenging problems.

There are about 235 million egg-laying hens in the United States. A laying hen produces roughly 250 to 300 eggs per year. In 2005, the population of the United States was estimated at about 295 million people. Ask some mathematical questions that you can answer using this information.

- About how many eggs are produced in the U.S. per year?
- How many dozens of eggs is that? (235,000,000 hens × 300 eggs per hen per year = 70,500,000,000 eggs per year; 70,500,000,000 eggs ÷ 12 = 5,875,000,000 dozen eggs.)
