Think about the progressing development of a baby as you match the sensorimotor substage and age with a description of what is happening with the baby.  Ex: Substage one is reflexes which includes sucking (survival – milk).  What would substage two be?  If you think it through, the matching of the substage and the behaviors being described just make sense.   Teachable moment:  Research today says much of what Piaget found is accurate….but some of the developments may occur earlier than Piaget claimed . (That would be because babies develop at different timing …”Individual appropriateness”) Match the sub-stages for the SENSORIMOTOR STAGE OF DEVELOPMENT with the best definition for each.
