What are some fourth grade word problems?

An example of a fourth grade word problem is, "12 students and 8 teachers went to the museum. Student tickets cost $6 each, and adult tickets cost $10 each. How much did the tickets cost in all?"

Fourth graders solve word problems with multiple steps, extra or missing information and that require estimating. Another example is, "A manufacturer makes 892 toothbrushes in an hour. Estimate how many toothbrushes will the company make in 19 hours." An example that requires ignoring extraneous information is, "Lisa brought 24 boxes of cookies to the school fair. Each box contained 12 cookies. She brought 13 boxes of chocolate cookies and 11 boxes of oatmeal cookies. How many cookies did she bring in all?"
