Take a non-transparent sack and several big objects that are well-known to the baby. The objects should be of a clearly defined shape and texture (e.g. clew of wool, keys). When the baby dives his/her hand in the sack, he/she defines by touch what object has he touched (at the first stage you can help by prompting). If several kids are playing, they puts their hands in the sack by turn – and pulls a “prize”. Babies like this game, where magic element is so strong. The only difficulty here is to select really different objects and not to forget about safety – the things mustn’t be sharp or prickly.
In the course of time the game is made more complicated. You can add smaller objects or toys that have slightly different texture. Or you can follow an easier variant and offer the baby to find definite objects in the sack (e.g. find a button or a key).
The game trains memory, imagination, develops tactile sensation.
