The document summarizes Stephen Anderson's presentation at IA Summit 2016 on creating concept models. It discusses playing a numbers game to add up to 15 as an example of a simple concept model. It then presents magic squares as a more complex concept model and compares it to tic-tac-toe. The document lists various models used to reveal patterns and concepts. It notes that while visual models are useful, the ones provided may not always fit the problem well and few know how to create new visual models. However, it suggests that all visual models are built upon common visual elements that can be used to make sense of complex ideas.
