Through two examples from daily life, I advocate the need to understand the development of mathematical thinking as a conjunction of touchscreen, gesture, speech, dragging, writing, pictorial-register, etc. Taking into account the context of production, this bundle has a significant role in the linguistic-cognitive spectrum of humans.
