In this lesson plan, the teacher aims to introduce vocabulary about family members to 5th grade students using fun activities. First, students will identify Simpson's family members from flashcards and match them to vocabulary words. Then they will listen to and sing along with a song about family while completing blanks with family member names. Follow up activities include ordering words to form family members and matching them to pictures, as well as a crossword to consolidate the vocabulary. The objectives are for students to learn and identify different family members and use expressions like "this is" and "I've got" to describe a family.
