Peer reviewed Peer reviewed
Direct linkDirect link
Bolyard, Johnna; Moyer-Packenham, Patricia – Journal of Computers in Mathematics and Science Teaching, 2012
This study investigated how the use of virtual manipulatives in integer instruction impacts student achievement for integer addition and subtraction. Of particular interest was the influence of using virtual manipulatives on students' ability to create and translate among representations for integer computation. The research employed a…

Good, Robert C., Jr. – Journal of Computers in Mathematics and Science Teaching, 1985
A pair of abacuses is used to illustrate addition, subtraction (by adding complements), multiplication, and division, with simplified examples given to illustrate the various features of each operation. Also indicates how this information can help students understand computer operations. (JN)
