Demo class question! Advice needed
I feel a little lost. This is my first formal job demo class at a private school. I do have experience at a public school in my country, I taught there for 1 year for my uni internship/social work. I’ll be teaching a demo class this Wednesday after passing the first interview. One demo class is for fifth grade and another for first grade (elementary). It’s a humanistic type of school. And I think I’ve done enough research about that these days, so I’m not struggling with their approach— yet. However I’m having so much trouble with planning the lesson. Bear in mind, right now I’m only getting through the lesson plan for fifth grade, haven’t even started with first grade.
The current English teacher sent me some information regarding the topic and material. She sent me a text, something like the following:
5th grade demo class
50minutes
21 Students
Unit: Flight
-vocabulary: parts of a flying machine
-describing types and parts of flying machines (using present and past simple of have/ don’t have)
-The hot-air balloons had…/ Modern planes have…
What I’m guessing is I’m supposed to teach only the parts of a flying machine and not the types, as she specified above. The thing is, she also sent two pictures of what looks like the class book. (Yes, only the pictures, not the name of the book or the book itself). But I’m so confused. It seems like the second activity is made for students to write which flying machine had which specific parts. However, I’m guessing they’re supposed to learn this with a listening at the beginning. I think they already went through that activity since it’s already completed as you can see the numbers there.
But, I’m not sure about this. How could I present the topic if they haven’t gone through that listening audio? Or if they did, what if they don’t remember it on Wednesday? How will they know which part goes with a certain type? I feel like I should give students a reading text, a sort of article or something that explains more or less what the listening explained. But I bet I’m never finding a text with that specific vocabulary. I already tried to find the name of the book, I even went through some popular textbooks that are available in pdf to see if I can get a little more info, but nothing. I don’t even know the name of the book. And even if I knew, I’m not certain I’d have access to it, since most are not available free and in pdf.
Another issue is the time. Will I be able to teach all of that in 50 minutes? I already planned like 15 minutes for greeting and some introductions, since they’re humanistic I bet they’d see well that I try to get to engage in that way with the students more, at least their names.
I know I could ask, but I can’t contact the teacher directly, she sent me that through the school’s psychologist number, she’s in charge of doing the interviews and setting the appointments for the demo classes and all. So I’m afraid me asking so many questions would look unprofessional and student-like. I already am and look very young, I don’t want them to think I need to be told what to do specifically or that I’m not creative, capable or professional enough to come up with a lesson plan with the resources they sent me.
Please, experienced teachers, I’d love your feedback no matter if you’re super experienced or if you have little experience. Every advice will be really helpful.
Ps: sorry if it looks like I’m spiraling, but I really don’t want to mess this up. (I think I AM spiraling lol)
