First, notions from commutative algebra are reconsidered from a geometric viewpoint. Affine varieties are introduced and endowed with a natural topology (Zariski topology) as well as a natural class of functions (regular functions). This also provides a more geometric perspective on the localization of commutative rings.

Second, projective and quasi-projective varieties are studied. These can be obtained from affine varieties through a gluing process. This gluing is an algebraic analogue of the way manifolds are constructed from local charts. If time allows, we introduce prevarieties and varieties in full generality.

Third, the notion of dimension in algebraic geometry is introduced. If time permits, we prove the semicontinuity of fiber dimensions. Additionally, we introduce Poincaré series and Hilbert polynomials to facilitate the introduction and comparison of various notions of dimension in algebraic geometry.

Finally, we delve into the local geometry of varieties by introducing tangent spaces and cones. In particular, we examine smooth points of varieties and establish a Jacobian criterion.
