This idea is not specific to any one school of education but the approach that I prefer is one that suggests having as few plastic objects as possible for the child's sensory experience. This is a great sensory activity for kids and they stay engaged with it for a long period of time. Be sure to change some of the objects in the basket every few days to maintain interest insha'Allah.
- Get a wooden/wicker basket and fill it with a variety of objects. (Ex. tennis ball, measuring spoon, fabric pieces, wooden spoon, baby food jar filled with beans - seal the jar with tap to avoid it being opened, ball of yarn, etc.). Avoid small objects that can present a choking hazard.
- Sit with the basket between you and the infant.
- Take an object out of the basket and explore it. Involve the infant in this process as much as possible (i.e. touch the infants hand with the object, hold the object under the infants nose, etc.)
- Allow the infant to explore the contents undisturbed for as long as he/she wishes. Leave the basket in a place where the infant can easily get it when he/she wants.
