Document Summary
Numerical equality: the realization that all sets of a certain number of objects have something in. Early number concepts common is the most basic numerical understanding. We have already discussed some information about infants" early number skills. Infants as young as 5 months old seem to have a sense of numerical equality as it applies to sets of one, two, or three objects. But not until the are 3 or 4 years old do children show a comparable understanding of larger sets, like four objects until they can count, they can differentiate larger sets. A quick and effortless perceptual process that people can apply to small numbers. One-to-one principle: each object should be labeled by a single number word. An object that is counted as 1 should follow the order. Stable order principle: the numbers should always be recited in the same order. Cardinal principle: the number of objects in the set corresponds to the last number stated.
