  2. 2. Rob Schupbach Problem #8 CRIN E07: Elementary Math Curriculum and Instruction Dr. Margie Mason/Ms. Rachael Cofer November 2, 2011 Answer: Jayla: carrot Travone: pencil Connor: football field Sandy: wheelbarrow Complete Solutions:1. Both a carrot and a pencil could be about 7 inches long. Both Jayla and Travone are thinking of objects about 7 inches long.2. Jaylas object must be the carrot. Since Travone is not thinking of a food, Jayla must have the 7-inch object that is food.3. Travones object must be the pencil. It is 7 inches long but is not food.4. A football field is very big. It is probably 100 yards long. That must be Connors object.5. The only object left is the wheelbarrow. Check that the clue fits the wheelbarrow. Yes, a wheelbarrow is bigger than a pencil but shorter than a football field. Houghton Mifflin Math. (2011). Retrieved November 2, 2011, from http://www.eduplace.com/kids/mw/g_5.html
