This handout on present tense verb endings is helpful for beginning Spanish students learning through TPR-S/Comprehensible Input strategies. (Note: The handout does NOT start with the infinitive form nor uses a traditional grammar table.) Instead, the handout starts with the "s/he" form and then explains how adding "-s", "-n", etc. changes the subject. The infinitive and nosotros forms are explained in more detail at the bottom.
For your convenience, the handout includes both a "1-per-page" and "2-per-page" option. Enjoy!
