Discrete mathematics has been recommended for inclusion in the school curriculum for more than 30 years. A persistent problem has been to establish a universally agreed-upon definition of discrete mathematics. We do not attempt here to present such a definition in the realm of mathematics, but instead give a curricular definition. We take this definition from the recent thorough survey paper by Sandefur, et al. (2022). We will present and elaborate this definition, provide rationale for it, and give some brief examples.
