underpinning the generalization of numeric-geometric patterns. Based on a video-taped Grade 9 classroom group activity undertaken by three students and framed by a cultural-semiotic theoretical perspective, we carry out a microgenetic analysis of an elementary form of mathematical generalization termed “factual”. We present a detailed analysis of the dynamics between oral speech and gestures.

Abstract
underpinning the generalization of numeric-geometric patterns. Based on a video-taped Grade 9 classroom group activity undertaken by three students and framed by a cultural-semiotic theoretical perspective, we carry out a microgenetic analysis of an elementary form of mathematical generalization termed “factual”. We present a detailed analysis of the dynamics between oral speech and gestures. Two main results are: the detection of intra-personal and inter-personal synchronizations between different semiotic systems; and the individuation of the key role played by objectifying iconic gestures.
