This study aims to examine effectiveness and problems in developing classes of handball focusing on "the motions of players without ball" in third grade in elementary school. In practice of lessons, the researcher set an outnumbered situation such as three-to-one or three-to-two and allowed students to play games taking turn in offense and defense. In addition, the researcher provided two conditions: 1) the area where defense can move around is limited 2) the offense always passes the ball to two grid areas. The results suggest that in the games turning offense and defense, players without ball managed to move on their purpose since the directions of goals became clear. Moreover, the results reveal that the outnumbered games were effective for players without ball to find the space far from their defense in the grid areas where they could pass and shoot ball.
