“…These results suggest that street vendors' informal learning experiences (i.e., those acquired in their jobs) have conferred these informal mathematics skills upon them. Additionally, children with more informal mathematics experiences, including playing games with numerical content and engaging in mathematics talk, also have higher scores in whole number comparison, estimation, transcoding, and arithmetic tasks (e.g., Benavides-Varela et al, 2023;LeFevre et al, 2009;Levine et al, 2010;Napoli & Purpura, 2018;Ramani et al, 2015;Siegler & Ramani, 2009). In informal settings, students may learn mathematics focused on the practical solutions for problems, and rely more on their intuition, tips from the context, and manipulatives than in formal settings (Hoyles et al, 2001).…”
