Standard: SSE.1a DO MORE Best Buy DVDs & CD s Task Your Grandma just sent you to Best Buy to purchase 2 Tyler Perry DVDs and 3 CDs of Miles Davis (only the best) at the prices listed below. After taxes, her total cost increased by $ How can you write the cost of 2 DVDs as an algebraic expression? 2. How can you write the cost of 2 DVDs and 3 CDs as an algebraic expression? 3. How can you write the cost of 2 DVDs and 3 CDs, increased by $5.60 for taxes, as an algebraic expression? 4. Your Grandma gives you a call and asks you to purchase instead 5 DVDs and 2 CDs, plus taxes. How much money will you have spent? Essential Questions: How are algebraic expressions different from algebraic equations? AIM: KWBAT: Identify parts of an expression such as terms, factors, and coefficients helping them understand the difference between algebraic expressions and algebraic equations. Standard: A.SSE.1a Interpret parts of an expression, such as terms, factors, and coefficients. _(Emphasis on linear expressions and exponential expressions with integer exponents.)

2 e Lesson AIM: KWBAT identify terms, factors and coefficients in expressions, and simplify expressions. Standard: SSE.1a The Language of Math Expressions Lesson Part 1 Expression Definitions. These vocab words are vital to speaking math. Algebraic Expression Variable Term Like Terms Coefficient Exponent Base Constant Factors Order of Operations Vocabulary Definition Examples a mathematical statement that includes numbers, operations, and variables to represent a number or quantity the factor being multiplied together in an exponential expression; in the expression ab, a is the base the number multiplied by a variable in an algebraic expression a quantity that does not change the number of times a factor is being multiplied together in an exponential expression; in the expression ab, b is the exponent one of two or more numbers or expressions that when multiplied produce a given product terms that contain the same variables raised to the same power the order in which expressions are evaluated from left to right (grouping symbols, evaluating exponents, completing multiplication and division, completing addition and subtraction) a number, a variable, or the product of a number and variable(s)
