The landing page for each chapter (e.g. https://teambasedinquirylearning.github.io/precalculus/2024/EQ.html) has a space for a big idea for that chapter. These need to be added in. The other books have these phrased as questions, e.g. "How can we measure the instantaneous rate of change of a function?" for the chapter on derivatives in the Calculus book.
