Break a scripture mastery verse up into words or phrases.
Write (or have students write -- even better!) a scripture mastery passage on pieces of paper or 3x5 cards.
Put the papers on the floor.
Read the scripture mastery verse aloud, stopping before the first word found on the papers. The first student to smack the correct paper wins.
This can be played as teams, with class members taking turns with the swatters, or in pairs.
This is another game my students just love!
