Answer:
past – danced
present – dance
past perfect – have danced

future – will dance
future perfect – will have danced
Explanation:
We form the Past Simple tense by adding <em>-ed</em> or by changing an irregular verb into its past form. e.g. danced
We form the Present Simple tense by using the root form of the verb or by adding <em>-s</em> or <em>-es</em> for the third person of singular. e.g. dance/dances
We form the Present Perfect from the present tense of the verb <em>to have</em> and the past participle of a verb. e.g. have danced
We form the Past Perfect form the past tense of the verb <em>to have</em> and the past participle of a verb. e.g. had danced
We form the Future tense by the form <em>will </em>and the root form of the verb.
e.g. will dance
We form the Future Perfect tense of the form <em>will have</em> and past participle.
e.g. will have danced
