Kindle Fire 7 - We have several of these tablets because they are so affordable. There are tons of educational apps that you can put on them from the Kindle App Store. Plus millions of Kindle books available to download. If you have Amazon Prime, there are hundreds of free books available through Prime Reading. We also have a subscription to Kindle Unlimited which allows us unlimited access to well over 1 million Kindle books (last I checked 1.8 million, more than we could ever read). We love it! There are fun chapter books that the kids want to read, fiction books, non-fiction books, children's books, even books that we can use for school subjects like history and geography. Totally worth the $9.99 per month.
