A straightforward way to teach personification is to explain what it is and give students examples of personification in stories. Explain personification to the students and use the examples to demonstrate how it's used. As the students get more comfortable with personification, they can read the examples and find the personification themselves. Finding the examples of personification themselves will help reinforce the concept in their minds.
After explaining personification to the students and giving them a few examples, write a class story that uses personification. You can provide the basic elements of the story and the students can provide details and the personification for the story. The students will likely enjoy being creative, and you can use it as an opportunity for them to apply what they know about personification to the class story.
Explain personification to the students and provide a few examples to them. When you feel they understand personification, give them examples of descriptions and ask them to identify which are personification and which aren't. This will help reinforce personification for them, and give them the chance to apply their knowledge. They can work in groups to identify the descriptions. Go over the examples of description as a class to make sure all the students understand how to identify personification.
Make a large pig out of pink butcher paper and hang it on the wall. Write short descriptions of the pig on white butcher paper large enough that the students will be able to see them. Some descriptions should use personification. After explaining personification to the students, use the pig so they can apply what they've learned. Give each student a description. Tell the students to tape the descriptions on the wall. Personification should be taped to the pig, while descriptions that don't use personification should be taped to the wall around the pig. When they're finished, go over the descriptions together and explain why the personification descriptions are considered personification.
