The teacher will teach 20 4th grade students about the parts of the digestive system. There are 10 girls and 10 boys, including 8 African American students, 2 Chinese students, and 10 white students. The lesson objectives are for students to recite the names of teeth and parts of a tooth with 95% accuracy after watching a video and labeling a study guide. The teacher will use a projector to show a video and introduce the class Facebook page for materials. Students will get a handout to label teeth and parts of a tooth and can access the YouTube video at home. The teacher will evaluate students by checking their classroom participation and having them write what they learned without materials to check understanding.
