The story, Julius by Angela Johnson, is about a little girl who receives a "pet" pig. A classroom pet show would be a fun activity to use with this story! I have done this type of pet show (not using real pets) just about every year I have taught and my students really enjoy receiving awards for their pets.
Each student draws a pet (they have or would like to have) and then writes about him/her. After school, the "judges" place the ribbons on the papers and then the next day the students get to see which one their pet was awarded.
