Algebraic reasoning in 3- to 5-year-olds


The current study asks when children begin to understand that when an object is added to a set, the numerosity of the set has increased regardless of set size. This knowledge can be expressed algebraically as ‘x + 1 > x’. In Experiment 1, 3to 5-year-old children were asked to reason about transformations (i.e., addition, subtraction, rearrangement… (More)
