Numbers, Divisibility, Negatives

This math unit begins with practice on basic divisibility rules, where students learn to determine if one number is divisible by another. The unit explores these rules through various difficulty levels, progressively increasing the depth of understanding required. Initially, the focus is on simple yes/no applications of divisibility, using different conditions to familiarize students with the concept in straightforward scenarios. The difficulty level then advances with medium complexity tasks that require a deeper comprehension of divisibility rules. As the unit progresses, students delve into prime factorization—distinguishing whether a number is a factor of other numbers by analyzing their prime factors in both values and variables. This segment of the unit emphasizes understanding the factorization, identification of common factors, and engagement with the greatest common factor (GCF). It culminates with targeted practice on determining if integers are common factors of pairs of numbers, consolidating students' skills in prime factorization, and providing a foundational understanding of factor relations vital for higher-level mathematics.Skills you will learn include:

• Divisibility rules

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:

• Divisibility rules
• Dividing by 2,3,4,5,6,8,9,10
• Factorization

This math unit progressively introduces and develops students' understanding and skills in handling negative integers through a variety of operations using number lines and arithmetic calculations. Initially, students practice identifying and locating negative integers on number lines, gradually moving to interpret these visual representations by plotting points and matching them with given integers. The unit then advances into operations, beginning with single-step additions and subtractions of negative integers depicted through movements on number lines. Students learn to translate these movements into proper addition and subtraction equations. Further, the complexity increases as they delve deeper into subtraction exercises, strengthening their familiarity and computational skills with negative values through multiple practice problems. The final segments of the unit introduce and practice the division of negative integers, reinforcing understanding of division rules with negatives and solidifying the concepts needed to handle various combinations of positive and negative integers effectively.Skills you will learn include:

• Negative integers
• Adding and subtracting negatives

This math unit begins with developing an understanding of determining the ones digit in products and exponents, starting with calculations involving small bases and progressively tackling larger bases and exponent values. Initially, students practice recognizing cyclical patterns of ones digits in small numbers raised to multiple powers. The unit progresses to include larger base numbers, where students continue to discern ones digit patterns through repeated multiplication and exponentiation, moving towards understanding the effects of varying power sizes on the final digits. Midway through the unit, the focus shifts towards prime factorization. Here, skills are honed in identifying whether an integer is a factor of another, using prime factorization to understand and check commonality between numbers, leading to an appreciation of greatest common factors. Concluding topics return to digit solving but with increased complexity: students work with both large and small exponents, exploring how exponent multiplication affects the ones digit when the exponents are identical or different. These exercises deepen conceptual understanding of patterns in ones digits within the framework of modular arithmetic and number theory, solidifying students' skills in pattern recognition and exponent manipulation.Skills you will learn include:

This math unit begins by introducing students to negative integers on a number line, starting with identifying and labeling positions and then progressing to using the number line for addition and subtraction of negative integers. As the unit advances, foundational skills in arithmetic operations with negative integers, such as multiplication and division, are developed. The exercises become more complex by requiring multiple operations with single and paired negative integers to solidify understanding and application of these concepts. The latter half of the unit shifts focus towards algebraic functions, starting with basic substitution of variables in simple and fractional terms involving negative integers. Students practice evaluating algebraic expressions by substituting specific integer values, including negatives, into equations and computing the results. The complexity increases as they deal with fractional terms, algebraic expressions involving power operations, and distributive properties to simplify expressions with bracketed terms and negative integers. This culminates in a comprehensive understanding of handling negative numbers within arithmetic and algebraic contexts.Skills you will learn include:
