This activity is a great way for students to review their knowledge of singular and plural possessive nouns. For this activity, they must create a possessive noun phrase (singular or plural) for each letter of the alphabet. Then, they must write the noun as a possessive noun. (For example, they must write: "the pile of the ant" / "the ant's pile".) Then, they can illustrate each phrase. My students really enjoyed this activity, and it was a great in-class graded assignment. It took us a few days to complete because it's rather lengthy!
