What are you waiting for?

A teacher asked a student to write 55.
Student asked: How?
Teacher: Write 5 and beside it another 5!
The student wrote 5 and stopped.
Teacher: What are you waiting for?

When I want to teach the coulors, I just ask my students to pretend the phone is ringing and they will answer:
Phone rings: ‘Green, green!’
They answer: ‘Yellow?’
They ask: ‘White?’
They hang up: ‘Pink!’
While teaching this use your hands pretending you are holding the phone.

Little Johnny: But I asked first!
