This slide show for sight words has common sight words for Kindergarten (probably a review for 1st). I incorporate this into my daily whole group Language Arts routine as a sight word review. Each word stays up for about 6 seconds then switches to the next word. You can have your whole class say the words and spell them together as they go by! It's nothing fancy - just an alternative to having flash cards all over your classroom!
Check out my blog for a more detailed description of how I use this in my classroom!
