For our 1st graders the principal will copy 2 books for each students. One will go home to practice and the other will be kept at school for pass off with the principal. This usually takes about an hour per class...Principal will take about 4 students down with him then each time a student comes back they will tell me how many students he wants. I give them their book and they go down to read. Gives a good twist to being in the Principal's office :) and learning these words. Students really enjoy this time to show them what they know.
