Draw a Math Story

From site:

This activity begins with the reading aloud of several math-oriented stories, identifies key mathematical vocabulary terms, models math story writing, and then gives students an opportunity to write addition and subtraction stories. Students first draw a series of pictures which depict adding more or taking away objects; they then write a correlating story to go with the pictures they’ve drawn. Finally, students share their stories aloud, and equations are written which symbolize the adding and subtracting written into the stories.

This is a very-well detailed lesson plan with resources and storybook suggestions.  Some teachers have adapted it to their middle school classrooms.
