I am a teacher, not an SEN parent, so I bow to the wisdom of others.
I am assuming from your post that they are preschool? So 3 or 4?
You need to think about something you want to learn, it is hard to know from your post what level you are at. Maybe getting them to ask for something. Then break that down into the smallest steps you can think of. So, ask to play with the train.
Are you using any sort of sign language?
The steps to that goal might look something like:
- recognise the word train when you say it and sign it
- go to the train when you say it and sign it
3 bring you the train when you say it and sign it
4 make the sign for train.
Then work on each step one by one.
Using picture cards to represent the day, with simple pictures on. Start with a few and gradually add on more.
Use these to structure the day, cards might be
food
nap/bed
car (for when you need to go out)
play /toys
bath
Then have a place where you put/stick the cards, so you have now and next
food and bed
and point to them and say them, using now and next. So, NOW we aree havign food, NEXT it will be naptime.
They gradually get used to the idea that the cards are showing now and next, you build up the cards, so you might add shop, Nanna's house, park etc etc
eventually do this as a book with velcro on the front, with space for about 4 cards, and the cards you use inside.
They can then also chose and card and give it to you, so they may ask for somethingusing the book.
