There are dozens if not thousands of Powerpoints like this beign freely shared by teachers. I dont pretend to be an expert on copy right or fair use but my understanding is that if somone allows a filel, like this one, to be downloadied, they are giving implicit permissio for it to be used. I think that that it would be a lack of integerity to claim this or tryt to sell it. In the mentime people are shariing some very good learning materials. Also , if you use a s earch engine like google and st type "topic:" and .ppt you will find a lot of files A search on "World War II .ppt: will produce hundreds of results. The problem is separating the wheat from the chafff. . Another trk I have found is that if you creat a dropbox folder( www.dropbox.com) and put the dropbod app on your ipad, you can play powerpoints . I am posting thhis here for all my friend with kids learning to read. i hope others find it useful, Bill McIntosh
