Mrs. Jacobs demonstrates how to multiply using the area model, starting with a review of one-digit by four-digit multiplication. She then explains two-digit by two-digit multiplication using the area model, providing detailed steps and examples. The video concludes with a final example and encourages students to review the material for quizzes or tests.
