**Functional Thinking**, the problem solving process we follow in our Labs, enables students to see and learn a powerful common form and format across much of K-12 mathematics. Take this Tour of a collection of typical Labs to visualize and experience what mathematics of the Digital Age could look like to students; where they solve problems by constructing a parameter table, then function tables to build a model, then graphs to analyze and iterate the model; and finally to ask *What if… *

We believe this Tour shows the power of **Functional Thinking** to make math problem solving a concrete, consistent, and understandable process across the discipline.
