After reading the book I would take out my easel and I would introduce to them what a Venn diagram is. I would explain to them that the one circle was the details of the one book and than the other circle is the details about the other book. Then I would explain that the middle part where the two circles overlap are the similarities in the books. I would explain that this is what comparing and contrasting is. I would ask the children to compare and contrast the two stories. I would ask for the details of "The Mitten" and then I would ask the details about "The Hat". I would then ask the children if there were any details that appeared in both circles. If there was I would then erase that information and then move it to into the middle section and explain that the reason I am moving it into the middle section because is appears in both stories.
After the group activity I would have the children go back to their seats and hand out a worksheet with a Venn diagram on it already. I would have the children choose two different animals for the stories. (one animal from one story and than the other animal from the other story)
