Divide the chalkboard into as many sections as you have zones/groups competing (2 to 4 groups works well). If you have a small chalkboard, have one zone representative at a time go to the board. Have a representative from the first one draw a picture of the scripture mastery selected by the zone without using any numbers, letters, or words. The first person in the class to identify and locate the scripture gets a point, or you may choose to give group points. You might also rotate into the artists place in each zone and compete with the students.
