The development of the mental representations of the magnitude of fractions.

The development of the mental representations of the magnitude of fractions.

We investigated the development of the mental representation of the magnitude of fractions during the initial stages of fraction learning in grade 5, 6 and 7 children as well as in adults. We examined the activation of global fraction magnitude in a numerical comparison task and a matching task. The...
