Warm- Up: Evaluate

Algebra A 1.1Variables and Expressions

Objectives I will be able to… –Interpret parts of an expression: terms, factors, coefficients –Write verbal expressions for algebraic expressions. –Write algebraic expressions for verbal expressions.

Definitions: Variable and Algebraic Expression

Objective 1: Interpret parts of an expression. Expression Term(s) Exponent(Power) Coefficient(s) 5+y 3

Objective 2: Convert variable expressions to algebraic expressions. How would we write these expressions in words?

Objective 3: Convert verbal expressions to algebraic expressions Verbal Expression Operation Algebraic Expression Three times x to the fourth power. 32 divided by “P” 10 less than the product of 7 and f

Partner Practice Two times “W” plus 6 The sum of “Y” and 12 Eleven plus 4 times “Z” Five times z to the second power plus sixteen.

Closing Thoughts/ Exit Slip Summary Portion Give me a DIFFERENT example of: –A variable –An algebraic expression –Writing a verbal expression to an algebraic expression. -Writing an algebraic expression to a verbal expression. –A real-life situation you might use this in

The Snake Activity. Directions 1.The item on the bottom of your card is a question. The item on the top of your card is the answer to another card. 2.Start the activity by reading the question on one of the cards. 3.Find the answer on the top of another card. Place that card under the previous card and read the new question on the bottom of the card. 4. Repeat steps 2 and 3 until all cards are in a line and the bottom question’s answer is on the top of your line/snake.
