Today I saw pictures of grocery bags that children decorated for Earth Day! The bags have messages and pictures about saving the Earth. The bags were used by supermarket customers on Earth Day. I solved addition and subtraction problems about the number of schools that decorated bags. I figured out that more schools decorated bags in 1995 than in 1994.
