We have a few sight word apps that the kids can use to practice with during Word Work time. The sight word apps that have different levels of difficulty in words (Sight Words) or different word feature focuses (Phonics Genius).
The kids choose a level and then work in the quiz game mode. When they choose a level, the screen will show about four words and the app will say one word from the list that they want the student to find. In Phonics Genius, the words in the list are all similar and the reader needs to really be aware of word endings to make sure they find the correct word. This is an area that a lot of first graders can use extra practice. The word lists can be very lengthy and the app doesn’t give you any idea of how close you are to the end of the list, but that is the only complaint that we have found. Both of these apps are free.
