A Comparison of How Textbooks Teach Multiplication of Fractions and Division of Fractions in Korea and in the U.s

To illuminate the cross-national similarities and differences in ways of teaching multiplication of fractions and division of fractions, this study compared the lessons on fractions in Korean mathematics textbooks and accompanying teacher’s manuals with the corresponding lessons on fractions in one U.S. reform mathematics textbook series and accompanying teachers’ manuals [Everyday Mathematics]. This study found that there is a gap between learning goal [intended curriculum] and problems presented in textbooks [potentially intended curriculum].
