Hola Janet

There are different lessons on how to form the imperative, and these lessons will test you so you need to work it out. Here are some:

Forming the imperative of tú for most verbs (affirmative commands)

Forming the imperative of tú for all irregular verbs (irregular affirmative commands)

Forming the imperative of tú (negative commands)

Forming the imperative of vosotros for all verbs (affirmative commands)

Forming the imperative of tú/ vosotros/vosotras (negative commands)

Forming the imperative for usted/ustedes/nosotros/nosotras (affirmative and negative commands)

You can add all these to your notebook and be tested on all of them.

I hope it helps.

Saludos
