Game of Hide the Watch
You can entertain your children for an hour with this game and at the same time, even without their knowledge, be training one of their most important senses.
Go into a quiet room and hide a watch where it will be out of sight but in a place where the ticking will be plainly audible. If the children are small it will be well to start with a small clock, or a watch which ticks loudly. Now let the children come into the room and, standing perfectly still, try to locate the watch by hearing it tick. Let them move around, but very quietly, so as not to disturb the others; or let all move at one time.
When one of them has located the watch allow that child to remain and assist you in hiding it for the others. A record can be kept to see who finds the watch the most often. One child must not be allowed to move noisily, or in any way disturb the efforts of the others. See to it that they use their ears and not their eyes; it will even be well to blindfold them.
