Mastering Prime Factorization, GCF, and LCM Concepts

Miss Wendell introduces a lesson plan focused on reviewing previously learned material. The class is organized with colored folders and notes, and students can earn bonus points by completing assignments with a score above 70%. The lesson covers prime factorization, greatest common factor (GCF), and least common multiple (LCM) with examples. Students are also guided through solving word problems and preparing for tests. The video emphasizes the importance of staying organized and completing assignments on time.
