**Guide to Modeling Scenarios and Technique Narratives**

**This is a growing list of resources and as developed, refereed, edited, and finalized, new materials will be published. To see how to contribute your own teaching materials go to Author Information.**

#### This Guide is organized to follow the topics found in a traditional differential equations course, hence, the numbering system reflects chapter sequencing in a standard differential equations text.

#### These materials are hyper-linked to Student Versions under Resources at https://www.simiode.org/ and they are available to all with no sign in or membership.

#### The link for each resource takes the reader to a resource page which may have more than just the document. In all cases a Click on the black Download pdf box in the upper right of the screen will produce the desired document.

#### Users must be registered and logged in to Teachers Group to see extended Teacher Versions.

#### Please use the Comments tab at each resource to make suggestions, point to corrections needed, relate experiences in your use of the resource, upload further resources we will add to the resource, discuss technical materials, and share your thoughts on the material. These comments will go to the author and the SIMIODE editorial leadership.
