This is perfect busy work for kids who finish first, small group work, centers, reinforcement for intensive/intervention groups, etc. Give the kids a singe die. They roll it and whatever number it lands on, they write the corresponding word on their paper.
Use it just for writing practice or turn it into a game... "first person to fill up their page (without cheating) wins"... "or which word will we write the most times"... "or how long does it take us to fill in all the words".
There are 17 activity pages which include all of the words 501-600 from the Fry Word List.
