This writing activity is a play on Laura Numeroff's series: If You Give A Mouse A Cookie, A Cat A Cupcake etc.
It is simple and when done, can be quite profound. There are 18 pages in each book, and students can work on the book together. Some pages feature a sentence the students must illustrate. Most pages feature the beginning of a sentence, the students must complete. Of course, each page must be illustrated by the student.
Pages 1-18 use the pronoun HE
Pages 180-end, use the pronoun SHE
This can be done at any time of the year, but Catholic Schools' Week is the perfect time to do this, or have it done by! Look at how Laura Numeroff's books are illustrated. Share the Numeroff series with your students so they get the idea. You can even find the books read on YouTube. If you are so inclined, hang them completed work on the bulletin board. You can also have the students take their books and bring them to another grade to read to them. It's simple yet effective.
