It's very useful to teaching grammar using real life pictures. To help students practice the lesson on the spot. Making small presentations with pictures and using the grammar that is learnt in the certain day. 

Grammar is a vast subject so we have to focus on the needs and level of our students when teaching,

However, taking first class of English grammar is almost same. Students are always keen to know that what is grammar and why we learn this boring and tough subject.

thanks for the invitation

 I agree with specialties answers

wait more details from experts on this field

I agree with Mr pardeeb answers, thanks for the invite. 

The question is not specific, because you may be teaching grammar to 6 graders or high school students, or to even pre-university students, and in each case it differs what the students already know and therefore, what is to continue from. I generally don't teach grammar as I teach literature to university students, but suppose I have to teach grammar, according to the standards of my students, I'll begin with the clarification of tense and time - why the form of verb changes in English and what other meanings it conveys than time change. Of course, I'd presume that my students are pretty clear about parts of speech and their syntactical roles.      

I start with Continuous usually 

Thanks for the invite, I apologize for the answer, I leave the answer for the professionals

Because I am not English teacher , I can't answer but here are 2 links for good ideas

Introduce Myself

After basic greetings, I introduce myself to the student(s). First, I will just give my name and nationality and then ask the student if he/she has any questions. This is a good opportunity to see if the student can form proper questions. I expect questions like "How long have you been teaching? / How long have you been living here?", etc. If the student does not ask any questions, I will give them a short outline of my teaching experience and qualifications.

Discuss Expectations & Goals

Next is the most important thing: identifying the needs of the student(s). Making an effort to understand what the student wants communicates that you are serious about helping him or her. I ask questions such as "What are your language goals? What do you want to focus on in class? How do you use or want to use English in your life? What do you think your strengths and weaknesses are?".

There is much to discuss under this topic. I may ask if the student has taken or plans to take any language tests. Also, I often ask the student to tell me about their previous English teacher and what they liked/disliked about him/her. This helps me learn how I can satisfy the student
