To conjugate a verb means making changes to the verb to say when it's being done and who is doing it. In Spanish this is done by changing the ending of the verb. Watch the video to learn how.
Use the -a ending with a singular subject. The -a ending is the same as the -s ending in English. What I mean is whenever you use -s with a verb in English, for example in The girl draws, you will use the -a ending in Spanish.
