Objective for Today’s Lesson  Students will be able to model relationships with variables, equations, and formulas. Why is this important?

Definitions 1.Variable: A symbol, usually a letter that represents one or more numbers. (Ex. x+3; x is a variable) 2.Algebraic expression: A mathematical phrase that uses variables, numerals, and operation symbols. (Ex. x+3; x+3 is a variable expression) 3.Equation: A mathematical statement that uses an equal sign. (Ex 3x+7=10 is an equation)

Write an algebraic expression or equation for each word phrase 1.Two times a number plus less than 3 times a number 3.The sum of 9 and k minus less than the product of t and 37. Rags to Riches

Write an equation to model the relationship in each table. Number of Days Change in Height (m) Time (months) Length (inches) d= number of days h= change in height h= 0.165d m= number of months l= length l=4.1m

Objective for Today’s Lesson  Students will be able to model relationships with variables, equations, and formulas.
