The research sample contains 76 student who are studying on class of a school in the city centre of Erzincan. The pre-test-past-test control group model was used in this study. Sample consisting of two experimental and one control group is aimed to determine the effective using way of virtual manipulatives. Application for all groups continued for 12 hours/3 weeks.
