This lesson plan outlines how to teach 4th grade students about identifying prime numbers using the SlideShare presentation tool. The teacher will ask introductory questions and have students work in groups to define and identify prime numbers. They will then share their answers with the class. Students will work on problems to practice identifying prime numbers and understand the concept. The objectives are to define, identify, and recognize prime numbers through class discussion and working on problems. The lesson concludes that grouping numbers by their factors is key to determining if a number is prime or composite.
