Each student needs their own pencil. Supply a piece of paper for each group. Call out a common noun.
Students are to think of as many proper nouns as they can that matches the common noun.
To make a competition between teams ask for complete silence. Make sure students are seated in a circle. Lay the paper in front of one student. Each student will get a turn to write a proper noun to match the common noun. The students silently pass the paper around the circle with each child writing their own answer.
