The use of multiple representations supports and requires tasks that involve decision-making and other problem-solving skills. [2] [3] [4] The choice of which representation to use, the task of making representations given other representations, and the understanding of how changes in one representation affect others are examples of such mathematically sophisticated activities.
The child was shown where the toy was hidden in the model and then asked to find the toy in the larger room. The children were able to find the toy on their first try in 54% of the trials. In another study, the symbolic object was made more accessible to the children with the expectation that dual representation would be more difficult to achieve.
However, they now can think in images and symbols. Other examples of mental abilities are language and pretend play. Symbolic play is when children develop imaginary friends or role-play with friends. Children's play becomes more social and they assign roles to each other. Some examples of symbolic play include playing house, or having a tea party.
An active area of research is to create and test teaching strategies to develop children's number sense. Number sense also refers to the contest hosted by the University Interscholastic League. This contest is a ten-minute test where contestants solve math problems mentally—no calculators, scratch-work, or mark-outs are allowed. [8]
At this point, most kids would have elaborated their calculations showing that each dime is worth $0.10, therefore making Bobby the owner of $0.40 while Amy's pennies amount to $0.30.
Egocentric thinking is looking at the world from the child's point of view solely, thus "an egocentric child assumes that other people see, hear, and feel exactly the same as the child does.” [4] This is consistent with the results for the preoperational age range as they selected photographs paralleling their own view.
Numerical cognition is a subdiscipline of cognitive science that studies the cognitive, developmental and neural bases of numbers and mathematics.As with many cognitive science endeavors, this is a highly interdisciplinary topic, and includes researchers in cognitive psychology, developmental psychology, neuroscience and cognitive linguistics.
