Fractions, Division Predict Long-Term Math Success

Turns out, knowing fractions and long division can predict overall math achievement.
Researchers led by Carnegie Mellon University’s Robert Siegler discovered that the understanding of fractions and division is a major source of the achievement gap between U.S. students and other countries, including China, Japan, Finland and others.

They studied two groups of students:
• U.S. students were tested in 1997 as 10-12 year-olds and in 2002 as 15-17 year-olds.
• U.K. students were tested in 1980 as 10 year-olds and in 1986 as 16 year-olds.

Regardless of time, geography, and other factors (parents’ education and income; children’s age, gender, I.Q., reading comprehension, working memory; and knowledge of whole number addition, subtraction and multiplication) – the importance of fractions and division for long-term math success was evident in both groups of children.

This research reinforces the importance of fractions – something numerous teachers told us during the conception and development of Motion Math, our fractions estimation game for iPad, iPhone, and iPod touch.
