15. Write, read, and evaluate expressions in which letters represent numbers in real-world contexts.

a. Interpret a variable as an unknown value for any number in a specified set, depending on the context.

b. Write expressions to represent verbal statements and real-world scenarios.

c. Identify parts of an expression using mathematical terms such as *sum, term, product, factor, quotient*, and *coefficient*.

d. Evaluate expressions (which may include absolute value and whole number exponents) with respect to order of operations.

[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]

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.
