This is a great product if you use the 1st grade Journeys reading series. It contains all of the sight words that are covered in this series. You can use them for your advanced students in Kindergarten and even as a review in 2nd grade. I use them on my classroom word wall to refer back to the words throughout the year.
Other ideas include:
Place the cards on a word ring for fluency practice.
Use the cards as flash cards for whole group practice.
Put the cards in a small group center for extra review.
The possibilities are endless!
