+## Motivation
+
+_Why is this important?_
+_Why do we want to learn/teach this topic?_
+
+The fundamental element for code-reuse is a function. For functions to be 
+useful, we need to parameterize them. Understanding how to do such is thus
+fundamental to programming in any language.
+
+## Topic introduction
+
+_Very brief introduction to the topic._
+
+Explain how to define functions with parameters and call them with values.
+
+## Foundational: Using reference types to avoid copies
+
+### Background/Required Knowledge
+
+A student is able to:
+
+* Explain what a function is
+
+### Student outcomes
+
+_A list of things "a student should be able to" after the curriculum._
+_The next word should be an action word and testable in an exam._
+_Max 5 items._
+
+A student should be able to:
+
+1. Call a function with any number of parameters using the same number of arguments
+2. Define a function with any number of parameters
+
+### Caveats
+
+_This section mentions subtle points to understand, like anything resulting in
+implementation-defined, unspecified, or undefined behavior._
+
+### Points to cover
+
+_This section lists important details for each point._
+
+* A function is called by invoking the name of the function, followed by parentheses
+* For each parameter in the function signature, a value must be provided, and in the same order
+* Multiple values passed to a function are comma-separated
+* When defining a function, you must list the parameters with the type first, and parameter name second
+
+## Main: Using references to modify external data 
+
+### Background/Required Knowledge
+
+### Student outcomes
+
+### Caveats
+
+### Points to cover
+
+## Advanced
+
+_These are important topics that are not expected to be covered but provide
+guidance where one can continue to investigate this topic in more depth._
