The teacher will discuss the different tenses of verbs and the time signals used in sentences. Normally, the teacher starts with the PRESENT TENSE verb, pointing out on the difference between singular and plural verbs, specifically when the verb needs an -s or no -s at the end of it.
The teacher DISCUSSES a new lesson.
(The subject TEACHER is singular, it has no -s at the end. The verb DISCUSS then needs an -s or -es at the end to show singularity.)
The students LISTEN to the discussion.
(The subject STUDENTS is in the plural form; it ends with an -s. The verb LISTEN is in its simple form, with no -s at the end.)
There can be time signals to help establish the present tense of the verb.
My dad always drives the car to go to work EVERYDAY.
My mother goes to the market ONCE A WEEK.
A 10-item exercise will then be given at the end of the lesson to gauge the student's level of understanding. More exercises can be given as needed.
At the end of the lesson, the student will receive a fully-recorded copy of the Skype conversation for reference.
