13 ) Write, read, and evaluate expressions in which letters stand for numbers. [6-EE2]

a. Write expressions that record operations with numbers and with letters standing for numbers. [6-EE2a]

Example: Express the calculation, "Subtract y from 5," as 5 - y.

b. Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. [6-EE2b]

Example: Describe the expression 2(8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms.

c. Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). [6-EE2c]

Example: Use the formulas V = s3 and A = 6s2 to find the volume and surface area of a cube with sides of length s = 1/2.

[MA2015] (6) 17 :
17 ) 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. [6-EE6]

Title: Factorials: Let's have a Dinner Party!
Description:

In collaborative groups of four, students will act out a dinner party where four dinner guests will attend. The students must act out the different ways to arrange four dinner guests. 

This is a College- and Career-Ready Standards showcase lesson plan.

Title: Burgers with a Side of Variables
Description:

In this activity, students will be writing equations using variables that represent different food items.  They will develop the foundational understanding of variables being used as a symbol to represent a number.  They will also write expressions using variables and then evaluate the expressions at specific values for the variables.

This activity was created as a result of the ALEX Resource Development Summit.
