Gesture and language are deeply intertwined, and attending to both simultaneously when examining mathematical processes is a complex yet rewarding task. We share our budding research methodology for analyzing gesture and language and discuss the methodology from a generic perspective that can be easily adapted to different contexts, participants, and mathematical domains. We further share our problem-specific gesture coding scheme as an example of the grain size and foci of such schemes. Finally, we close by discussing the importance of gesture and language to understanding mathematical justifications and proofs.
