SO how would you explain this to a Creole student when the sentences only use one verb? Ex: Corn was planted. Mayi plante. or I am going home. M ale lakay. or I will see you tomorrow? M ap we w demen? All 3 ex use PS and PP. No helping verb used.

You're right, no infinitive form is used here.
Corn was planted - Yo te plante mayi (past tense of the verb 'to plant')
I am going home. - M prale lakay (PP of verb 'to go')
I will see you tomorrow. - M ap wè w demen. (Future form of verb 'to see')

Examples of instances where infinitive form is used:
They're going to plant corn. - Yo prale plante mayi.
I am going to go home. - M pral ale lakay.
I am going to see you tomorrow. - M prale wè w demen
