UNIT 8: Data Analysis (13 Days: 1/19‐2/5) UNIT FOCUS: Parenthesis, brackets, simplify numerical expressions, problem solving, patterns in a table or graph Enduring Understandings: There is an agreed upon order for which operations in a numerical Essential Questions: expression are evaluated  An algebraic expression has at least one variable and one operation. How can you find a rule and write an expression? A variable is a quantity that can change and is often represented How can you evaluate a numerical expression with more than one operation? with a letter What order should you use when you simplify an expression?  Algebraic expressions are mathematical phrases that can represent real‐world situations.  Sometimes patterns can be used to identify a relationship between two quantities. A multiplicative pattern between two pairs of numbers can be used to write a rule using either multiplication or division.
