Probably what you say at the beginning of your lesson will depend on whether you are a class teacher or a specialist teacher, as well on the age and level of your pupils.
Here you are some of my attempts for the different scenes:
In the book mentioned in the main post of the section, you can find different ways to start a lesson as well as different useful expressions and sentences. The following ones have been completed by me, with a little help from the book:
Check attendance
Is everyone here?
Is anyone missing?
No-one missing?
Then we can get started.
Sing a song
Today we’re going to start by singing.
Do you remember the song we sang yesterday?
Are you ready to sing it again?
Rearranging the classroom
We need some more space for today’s lesson –you there- can you help me move some tables back?
Today we’re going to work in groups of four, so stand up and, quietly, move your tables to make your groups as you did last week.
Do question routines
So today is Monday, isn’t it? Isn’t it? What day is today? Tuesday? Saturday?
It’s a lovely day, don’t you think? What’s the weather like? Is it cloudy? Is it rainy? Is it foggy? No… Ok, it’s sunny.
Take the register
Ok, now let’s take the register.
Ok, let’s call the roll to check if everyone is here.
Play a game
Now we are going to play a game so you need to pay attention because I’m going to give you a demonstration.
Today we are going to try a new game, so please stand up quietly and come to the front of the classroom.
Say a rhyme
Do you remember Humpty Dumpty? Everyone together: Hampty Dumpty sat on a wall… […]
Now I’m going to repeat it and you have to say ONLY the last word of each sentence, ok?
