We report a study on mathematical literacy with special emphasis on health literacy. In particular, we identify and characterize the mathematical competencies that a citizen needs to interpret the official information on the COVID-19 pandemic as experienced in Mexico. To achieve this, we analyze the daily reports on the pandemic issued by the Mexican Ministry of Health, using the framework of mathematical competencies as a theoretical lens. Our results show that there are five necessary competencies to interpret the official information: mathematical communication, mathematical representation, mathematical symbols and formalism, mathematical modeling, and mathematical reasoning competency. After characterizing and illustrating these competencies, we close the paper with a reflection on the importance of mathematical literacy in a pandemic world.

This article describes the implementation of a teaching strategy aimed at middle school students (aged 11–12 years) for the study of motion as a linear function. The activities were designed to promote a discussion about the variables involved, their relationship and variation, as well as the construction of graphs based on the experience of movement. The students used digital devices, such as cell phones, to record a variety of motion scenarios and used Tracker software to analyze the motion.
