In most cases, you use "s" on the end of verbs whenever the subject of the verb is singular and third person. Like in your example, "The teacher guides the students." Or, "He/she/it guides the students." Whenever the subject is plural, or whenever the subject is "I" or "you," you wouldn't use it. For example, "The teachers guide the students." "I/you guide the students."

when using the present simple tense to talk about facts and repeated habits or actions, we use the first conjugation of the verb. we add "s" "es" or "ies" to the verb when the subject is third person singular here are some examples: 1-I like tea. 2- he likes tea. 3- she washes the dishes every Friday. 4-Anne always studies hard.

Present Simple ( it - He - She ) >> Verb + s example : He teaches English Sara < ( she ) Likes her room John drives a taxi. ..................................... ( I - They - We - You ) + verb Examples : I live in New York. We meet every Thursday. We do not work at night. ................................. http://www.englishclub.com/grammar/verb-tenses_present.htm
