Manage sight words and monitor student progress using this Rainbow System .so many good ideas on here.MUST READ! I think you should type all the words out and group them by six weeks in color, and then divide them by week in a card box with dividers.
Zap game I learned in grad school. Put high frequency words on sticks (these are foam sticks) and write zap it on a few sticks. The kids pull sticks from a container and read the words. If someone gets Zap It, all of the sticks go back in the bin.
