Some resources for undergraduate and graduate level mathematics, mostly coming from classes I taught or mini-courses I gave.
From Classes
Exploration of the Projective Line (Math 619, Riemann Surfaces - a series of exercises aimed at understanding the geometry of the projective line, from its definition as a set to the sheaf cohomology groups of line bundles).
Discovering the determinant (Math 469, a series of problems introducing determinants in terms of functorial properties of wedge products)
Differential forms for Calc 3 students (Math 261, a handout whose main goal is to show that there is but one Stokes' theorem).
From Activities
Plane Algebraic Curves/Curvas Algebraicas Planas (Mini-course for EMALCA, Liberia, February 2024).
Introduction Tropical Curve Counting (Mini-course for undergraudate students at Universidad de Costa Rica, August 2019).
Introduction to Moduli Spaces (A cycle of lectures at Universidad de Costa Rica):
Lecture 1: Enumerative Geometry and Moduli Spaces
