National Geographic, Reach for Reading High Frequency/Sight Words for 1st grade.
Includes all 8 units!
Organized to be all in one place to help with data tracking for each student. Highlight the words as students master them and keep record of the words they are struggling with to help with spiral reviews.
I clip all of my students' packets together by reading group. When they come to me on Friday it's quick and easy to test each one. The units for each set of words is clearly labeled so there is no hunting to find the words for that week's learning.
