This is the recording sheet I use to track my kindergarten students knowledge of the sight words and Dolch words taught in our kindergarten curriculum. Some words on this list can be sounded out, but I only give the students credit for the word if they have mastered it.
This list has 108 words and can be used as a guide for the goal of mastering at least 100 words by the end kindergarten! You will be amazed how quickly some of your students will master this whole list. Just set the goal (and maybe give a few incentives).
