This file contains three pages with some key verbs in Spanish: the present tense, preterite, imperfect, future and conditional of regular verbs and the same tenses for irregular verbs ser, estar, tener, ir, poder and haber. The tables also include how to form the present participle and the past participle.
This resource is a free sample of a much more extensive resource, my Spanish GCSE grammar booklet, which can be found in its full form in this link:

The full booklet is 63 pages long, and I have included a copy of the contents page as part of this resource.
