Here is an edited version of a 45 minute lesson I do with students to introduce the concept of Grit to elementary students. Modifications of this lesson have been done in grades K-6! After this lesson we read Leo the Lightning Bug and students hold up an index card with th word GRIT on it when they notice the main character showing grit. After that, I show the Brave clip and the students do the same as "Grit Detectives"!
