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.

D. amphetamines became available from illegal laboratories rather than legitimate pharmacies
Explanation:
Due to the amendments to federal drug laws known as Drug Abuse Control Amendment of 1965, amphetamine became available from illegal laboratories rather than legitimate pharmacies. Prior to the amendment drugs like barbiturate, amphetamine and lysergic acid diethylamide (LSD) could easy be gotten from pharmacies but the amendment restricted the availability of such drugs. The amendment was as a result of increase in drug abuse among the American population.
