X ÷ 4 = 8 ConstantVariable Operation Equation Constant

Agenda 2) Brainstorm Vocabulary/signal words for math operations (+, -, x, ÷) 4) Complete a handout (4 problems as a class and the rest independently) 3) Identify key words/signal words in verbal expressions (Class example) Goal: Translate verbal expressions into algebraic expression 1) What does it mean to translate a verbal expression to an algebraic expression 5) After independent work is completed including challenge (must be looked at by adult), HW will be handed out to begin in class

Verbal Expressions ⇒ Algebraic Expressions When things are written in word form (like a word problem) Expression is part of an equation, it does not have an = sign (*is not in word form) Example: Jack has 12 more cupcakes than Jill Example: 12+J

Addition (+) Subtraction (-) Multiplication (x) Division (÷) increase more total both altogether sum combine less decrease minus take away spend how much more gave left difference times product double triple split share half quotient

Underline the signal words in this verbal expression. Write the sign above it. Write the algebraic expression. The sum of Y and R The quotient of 15 and d The difference between 23 and C Twice the sum of 10 and Jane's number of books

Problems from handout the sum of x and y 7 more than x b decreased by 4 the product of x and y twice the sum of 5 and b the quotient of 12 and b Mrs. Reed's big cat, Todd ate 3 times as much food as her little cat, Harry.
