Prime Factorization - Factor Tree with 3 Factors - Explain (Level 1)

This math topic focuses on the skills of prime factorization and understanding factor trees with three factors. It involves interpreting diagrams to determine how product pairs relate back to their original numbers, thereby testing comprehension of how to break down composite numbers into their prime factors using factor trees. Each question provides a set of potential answers where students must select the correct multiplication pair that correctly corresponds to the given number in the factor tree. This is an introductory activity that helps reinforce understanding of basic factors and multiplication.
