 C++ Compilation model allows the developer to seperate their 
-declarations and definitions into vrious files to build 
-separately and potentially in parallel so as to reduce rebuild times, 
-reduce file sizes and scopes, avoid naming collisions, and producing 
-compiled libraries.

 ### Foundational: Building code from multiple files
 
 #### Background/Required Knowledge
 
 A student:
 
-1. Knows how to define a variable, function, or class
+1. Is able to define a variable, function, or class
+2. Is able to access declarations from either module import or header inclusion
+
+Questions:
+modules and/or functions?
