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
