20 Lists of words 2nd graders should know how to read + a sheet to place stickers/stamps on when each list is completed with no hesitations or mistakes.
Sight words are words that students should see and know on sight (recognize them visually).
This improved my second graders reading tremendously and allowed them all to go at their own pace. Each student had a folder with page protectors and the sticker sheet glued to the front. They would receive the next list of sight words once they demonstrated that they had mastered the current list.
With my first graders I had one page protector and kept the rest of the lists in the folder pockets which made for lots of lost and torn lists.
With my second graders I put in 10 page protectors in each folder and placed the lists like a book.
The students were always excited to read their sight words and practiced them for homework and at recess.
