Objective for Today’s Lesson  Students will be able to identify variables, numerical expressions, and variable expressions. Also, students will be able to write variable expressions for words and phrases. Why is this important?

Definitions 1.Variable: A letter that stands for a number that is unknown. (Ex. x+3; x is a variable) 2.Numerical expression: A mathematical phrase that uses numerals and operation symbols. (Ex 7+3; 7+3 is a numerical expression) 3.Variable expression: A mathematical phrase that uses variables, numerals, and operation symbols. (Ex. x+3; x+3 is a variable expression)

Identify each expression as a numerical or a variable expression. For a variable expression, what is the variable? NumericalVariable

Write a variable expression for each word phrase 1.Nine more than a number y 2.4 less than a number n 3.A number z times three 4.A number a divided by times the quantity 4 plus a number c Rags to Riches

Measurement. Write an expression for each quantity. 1.The number of days in 4 weeks 2.The number of days in w weeks 3.The number of pounds in 160 ounces 4.The number of pounds in z ounces

Objective for Today’s Lesson  Students will be able to identify variables, numerical expressions, and variable expressions. Also, students will be able to write variable expressions for words and phrases.
