1.) To show a negative declarative sentence, use non- Manual marker of shaking your head. In slang , this is smh.
2.) To show an affirmative declarative sentence, use the non-Manual marker of nodding your head. This shows it is a yes or correct answer.
3.) Signing Me Teacher Me while shaking your head means I am not the teacher. Since shaking your head is a negative.
4.) You can change the sentence "I am not hungry" into " I am hungry" with a non- Manual marker by nodding your head.
