Divide the SM into phrases (or lines from the SM card). Number each phrase or line. Assign each student a number (several students should have the same number). Give a few minutes for students to memorize their line. Call up a student per phrase/line and have them recite the SM (each their own line). Then call out a number and who ever in the audience has that number will come up and replace the person in line (who had that same number). The line will recite the scripture again. Call out several different numbers. Repeat this process until all students have had a chance to be up front in the reciting line.
