Even when catching and throwing, you can learn to throw in clearly defined directions. Both hands are used. The children throw a ball to each other at the same time. One side should throw down the line, the other crosscourt.
Correction:
It is important that the kids also throw in clearly defined directions, so crosscourt really means throwing diagonally so that an angle is created. And down the line means straight ahead. The balls must be caught on the side, not in front of the body.
