You might find that negotiating with privileges in exchange for activities works better. Teenagers are no exception. We offered our teenagers many suggestions, and they had a few of their own. Here are the most popular activities we came up with as a starting point for parent-teen discussion. But quite a few just require a library card.
Summer gives ample time for any teen to achieve a typing goal.
Others who can already type might benefit by increasing performance factors like speed and errors. Back in the days of manual typewriters, even before erasable bond, I taught myself how to type using a book borrowed from the library. These days many libraries offer free use of on-site computers for tying or accessing the Internet, as well as typing books to check out. Bookstores are another readily accessible source for typing how-to books. Perhaps your teen balked at the sight of that typing book.
