A combination of those methods is seen in the emergent curriculum concept in the sense of making the learning fit the interests of the children and what is age appropriate for them. I love having a large collection of books and files on my computer meaning if we see something interesting on tv or in a book ex. Are we there yet goes to a dinosaur dig or Bob the Builder makes a windmill. I can then get a book on the topic and print a picture to colour to go with the topic. We can then extend it with toys, supplies, whatever we have on hand and then continue it the next day if interest is still there.
