Provide the resources for stimulating play. Simply having objects to play with appears to be an important component of later intellectual development. Why? Toys and play materials provide the stimulus for children's exploration. When these things are interesting to children, children learn more from them. Toys and play materials are also centerpieces for interaction. When toys are interesting to them, you are more likely to see children coming together and united in a common activity. What do we all do when we are playing together, rather than alone? We talk more, create more, and engage more. These are the foundations for learning.
The availability of free games that you can play negates the issue of thinking about cost. All you have to do is make sure that you have reliable Internet if you need to play the game online. You can also update your flash player. Flash games can fail to play if your flash drive is not updated. These games can be played by one player or more depending on what you need. Those that are played online can be played by players in different places. This makes it a platform for networking and communication in general.
