This math unit focuses on enhancing number sense and understanding divisibility through digit solving and prime factorization. Initially, students practice identifying the ones digit in multiplication products and factors, nurturing their ability to recognize numerical patterns and deduce feasibilities in basic multiplication. The unit progresses to explore the ones digit in powers with small and large bases, transitioning from simple multiplication to understanding exponents. Here, students develop a deeper grasp of cyclical patterns of digits when numbers are raised to various powers. Further complexity is introduced when handling numbers raised to high exponents, solidifying their recognition of patterns in modular arithmetic. The unit culminates with in-depth exercises on prime factorization. Students learn to determine if one number is a factor of another and assess common factors between numbers through prime factorization represented both in variable and numerical forms. This series of topics not only builds foundational skills in arithmetic and algebra but also strengthens problem-solving abilities with a focus on factorization and divisibility rules. Skills you will learn include:
