Unit 72

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.more
