I can give examples in several different contexts of what art is and being creative is.
What do we now know about Art -
Alice big girl art is staying in the lines and scribble is baby art. I would use shapes to make art.
Anna- you can fold a piece of paper and create a heart and cut it out.
Gauri can paint colour and draw and cut stuff out.
Oscar B- You can make art with old rubbish. like recycling things.
Eloise- cartoons are art they are fun.
Chenuthi- art can be music and dance too.
