I have created an Excel sheet with all Dolch sight word lists. I have used this to track my first graders progress with their sight words throughout the year. I feel that having all the words in one place is an easier way to get an accurate measure of how many words my students know. :)
The best part is you can use this one sheet throughout the year if you want! Each time I assessed my students, I used a different pen to mark the ones they miss and mark the date using the same color.
Hope this helps!
