GAIMME: This is the Guidelines for Assessment and Instruction in Mathematical Modeling Education report produce by the Society for Industrial and Applied Mathematics (SIAM). Although a bit general and detached from classroom practice, it has some interesting problems and frameworks for mathematical modeling.

Introduction to Mathematical Techniques Used in GIS: Written by Peter Dale, this was the starting point and the organizing tool for the topics I wanted to cover.

Fundamentals of Geographic Information Systems: Written by Michael N. Demers,this was a guiding text for understanding the more general field of geographic information systems. It also provided insight into how topography is mapped.

Moody’s Mega Math Challenge® 2017: SIAM also offers a math challenge every year and the 2017 problem regarding National Parks was the one that got me thinking about how to involve students with the outdoors.

Sustainable Development Goals: Put together by the United Nations (UN), these 17 goals are to be achieved by 2030. These can inform projects in all content areas, though I have chosen to focus on education and the environment.

The Mathematical Sciences in 2025: This was a helpful document on some of the predictions as to where math is headed. The strength of the document is the biographies of individuals working at various frontiers.

List of Unsolved Problems in Mathematics: Although this is a Wikipedia page, it is an impressive list of problems that have yet to be solved.

The Millennium Problems: Written by Keith Devlin, this book is a good general introduction to the seven problems that have been highlighted by the mathematical community as vitally important to prove. Better yet, each one has a one million dollar prize attached to it.

Three Acts of a Mathematical Story: Dan Meyer does a great job of describing what he sees as the true process of mathematical thinking and the future role of teachers.

Modeling Climate Change: Although I did not end up using the materials from this course, when I first thought I would be working on the mathematics of climate change, this course was a good introduction to algebra-based models in Excel.
