#Arcavi (2005), "Developing and using symbol sense in mathematics" define e explora o conceito de "sentido de símbolos" (symbol sense), uma atitude flexível, intuitiva e cheia de significado em relación á linguaxe algébrica e simbólica na matemática.

"Arcavi (1994) describe esto como encontrar significados no
equivalentes a partir de expresiones equivalentes." (p. 57)

Al enfrentarse a un patrón visual o numérico, los estudiantes realizan un conjunto de acciones físicas y mentales que articulan el paso de la observación a la simbolización formal. Arcavi et al. (2017) estructuran este proceso en cuatro momentos interconectados:

Si quieres enseñar #álgebra de verdad, primero tienes que verla como la ven tus alumnos.
No desde tu cabeza de adulto que ya la domina, sino desde la de alguien que acaba de llegar.

Today is the fourth day at our "Rigorous Illustrations" conference at the Institut Henri Poincaré. We take a look at #illustratingMath in Education with talks by Zsolt Lavicza (Technology), Stacy Brown (Geometric Proofs), and Greisy Winicki Landman (Role of Visuals). (1/3)
A photograph of Zsolt Lavicza presenting in a large lecture hall. He is standing to the right of a large blackboard, wearing a black jacket and glasses. Behind him, a projection screen displays a slide titled "STEAM Education Innovation Research & 3D Modelling" with various diagrams and flowcharts related to educational ecosystems and 3D innovation. Two microphones are positioned on the desk in the foreground. A photograph of Stacy Brown giving a presentation in a lecture hall. She is standing in front of a large blackboard with hand-drawn geometric figures. The projection screen above her shows a portrait of Henri Poincaré and a quote: "geometry is the art of reasoning well from badly drawn figures; however, these figures, if they are not to deceive us, must satisfy certain conditions." She is mid-gesture, looking toward the audience. A photograph of Greisy Winicki Landman presenting in a lecture hall. She is wearing a dark jacket and blue jeans, gesturing with her hand while speaking. Behind her is a large, clean blackboard and a projection screen displaying a multi-colored quote by Arcavi (2000) defining "Visualization" as the process of creation, interpretation, and use of pictures, images, and diagrams to communicate and develop ideas.
