One of the most important predictors and components of mathematical achievement has been found by Siegler and colleagues as the skill in placing numbers, including fractions, on a mental number line.
Siegler's theory of these mathematical developments aims to develop strategies to improve children's math learning.
Some of Siegler's studies are aimed at representing children's numbers to identify the learning of whole numbers, fractions and other arithmetic topics.
Therefore, these studies on the development of children's math skills are very useful in identifying why some children are more proficient than others and in identifying the strategies used by children to solve math problems.
