In this module students develop their skills at translating verbal expressions into mathematical ones. This is a crucial skill that often doesn't get enough attention. A student's ability to successfully translate words into mathematical expressions and equations puts that student on a path to successfully solving more complicated problems.

In this module students focus on addition expressions. This includes numerical and algebraic expressions. They work on addition expressions of the following form:

• a + b, for various integers a and b
• x + a, for integer a
• ax + b, for various integers a and b

As an extension of their work with translating words into mathematical expressions, students explore the various symbols used by meteorologists with weather maps. Students analyze the symbols on a weather map. They also translate words into mathematical expressions using the context of weather.
