These videos you can watch with your children and then you can find some games below. 🙂

First of all there are not only two videos, there are two playlists: the first one consists of 47 videos, the second of 90. Secondly these video represent only letters, not reading rules, not pronunciation rules. If you would like to know where it should be read the letter “O” as “O” and in which words as “A”, you can go here http://wp.me/p6HQJC-1i
