Peer reviewedFuson, Karen C.; Kwon, Youngshim – Journal for Research in Mathematics Education, 1992
Thirty-six Korean first graders were interviewed to study their ability solving addition problems with sums of 10, single-digit sums between 10 and 18, and subtraction problems with minuends between 10 and 18. Finger methods to show sums over 10 and the regular named-10 Korean number words supported their learning of 3 efficient recomposition…
