Warm-ups!Each day we will complete a warm-up. This is the warm-up structure:
Draw this out on your own paper or print it from the website each week.

Variable
Algebraic Expression: A mathematical phrase that can include numbers, variables, and operation symbols (ex. 3y + 7)Coefficient: A number that is multiplied by a variable (ex. 5x)Constant: A value that does not change (ex. 4)Distributive Property: For every real number a, b, and c: a(b + c) = ab + ac and a(b-c) = ab – ac (ex. 4(x + 3) = 4x + 12)Equivalent Expression: Expressions that have the same value for all variablesIntegers: Positive and negative whole numbers (ex. 22, -3)
Like Terms: Have identical variables; that is, they have the same variable to the same exponent. Constants are like terms as well. (ex. 6x2 and 99x2 are like terms)Order of Operations: Parenthesis, Exponents, Multiplying and Dividing (left to right), Adding and Subtracting (left to right) PEMDAS!Simplify: To write an expression in simplest form (combine all like terms)Substitute: To replace a letter with a number or algebraic expression
Term: “parts” in an expression that are added or subtracted (ex. 4x2 + 3 -> 4x2 and 3 are terms)Variable: a letter that represents an unknown number
