Lesson 2: Writing Expressions to Represent Real World Scenarios

Content Standards and Objectives M.6.EE.6 (CCSS6.EE.B.6) Use variables to represent numbers and write expressions when solving a real world or mathematical problem; understand that a variable can represent an unknown number or depending on the purpose at hand, any number in a specified set.

Variables Represent Unknown Values Sally sold cupcakes for a school trip X = the number of cupcakes sold

Writing Expressions Sally sold cupcakes for a school trip. Each cupcake sold for $2.00 Let x = the number of cupcakes 2x

Now, try an example on your own.

The amount of flowers in the garden tripled

Let x = the amount of flowers Mathematical operation – Multiplication Value – Tripled – 3 3 ● x Or 3x Writing Expressions
