Unit 79
This math unit guides students from understanding prime factorization to mastering the identification and application of the Greatest Common Factor (GCF) across different numbers. Students begin with exercises that simplify numbers into their prime factors using factor trees, enhancing their initial familiarity with factorization. As the unit progresses, learners utilize Venn diagrams to visually identify common factors. This approach not only aids in finding the GCF for pairs and sets of three numbers by recognizing overlap in factors, but also challenges students to discern GCFs from more complex diagrams and factor relationships. Subsequently, the unit integrates the use of variables and algebraic expressions in factorization, deepening students' ability to work with abstract representations of numbers. By the end of the unit, students are adept at applying these skills to solve problems that require identifying the GCF and understanding the underlying factor relationships through both numerical calculations and visual aids. Thus, establishing a robust foundation in factorization that supports advanced mathematical concepts and problem-solving.more
