Intelligence cards are units of information presented to children in an appropriate manner.
 
They are visual stimuli accompanied by an auditory stimulus, which involves saying out loud what is being presented. Intelligence cards are grouped into categories that refer to a specific topic and usually come in sets of 10 images.
 
Each set of cards features an image that has been studied and designed to capture the attention and concentration of a baby from 3 months to 4 years of age.
