Mathematical Modeling, National Curricular Base, Numerical Simulations, Discrete Mathematical Model, COVID-19.

In this work we present a discrete mathematical model of the SIR type, which is applied to realistic data relative to COVID-19 using mathematical methods and numerical simulations to obtain results regarding the measures of prevention to reduce contagion taking into account social distancing and the use of face masks. From the study of the model, as well as the tools used, we make some remarkes abont the use of Mathematical Modeling as a tool aligned with the Common National Curriculum Base aiming at teaching and learning mathematical topics present in the high school curriculum, whose objective is to contextualize mathematics using the problem of the pandemic caused by COVID-19, providing to high school students a better understanding of applications of Mathematics.
