Here is a great game to give your students some extra practice for finding greatest common factor (G.C.F.). There are a total of 26 task cards that can be used independently of the game board so this is a great product to use with your early finishers too!
Another idea that has proven fun in the classroom is to scatter the task cards around the room and have the students complete the activity as a scavenger hunt! My students loved it! Learning is fun again!
