Hi
page 299 and 300 of the level 3 handbook goes into greater detail for each of these areas of children's holistic development.
If you think about how language is involved in each of the 'situations' you'll see how it links/is involved with children's overall development.
Quote:
Play is important for children. it provides pleasure as well helping them to learn and socialise. As children's language develops, so too does the ay that they play. Play becomes more cooperative, complex and imaginative. Communication also plays a large part in playing with others, so again supporting children's communication and language helps their play.
Best wishes
