On Thursday, July 17th, 2025 we were invited by En Casa con Glasswing to run a Math Playtime aimed at 10 to 13 year-old kids. In this virtual event, the participants from all Central America explored the fun activity «Cryptosums» (in Spanish) with our volunteers Romina Busain from Argentina and Marleny Vargas from Panama.
