Educational toys are great, but the best way to help children learn is to have them participate in activities that involve interaction. Talking, playing, and using the imagination are great ways for children to learn.
The best way to find out if you qualify is to look on the internet for grants and check the websites for requirements. If you meet all the requirements it states, or if the site doesn't state requirements, go ahead and apply. It is better to apply for as many grants as you can rather than only a select few, as there is lots of competition for grants.
