In this study, the expectations of middle school students' parents regarding to "conceptual understanding and active student participation" "positive attitude and behavior attitude" and "authority and rule-oriented teaching" were examined. A valid and reliable threefactor instrument developed by the Aytekin, Baltaci, Altunkaya, Kiymaz and Yildiz (2016) was used in collecting parents' expectations. 749 parents participated in the study. It was found that the variables of parental gender, parental age range, and monthly income of the parents, level of loving mathematics and level of helping the child have no significant effect on the expectations. The university graduates had less authority and rule-oriented teaching expectation than the remaining parents. Besides, it is seen that the 5th grade parents had higher expectations of conceptual understanding and active participation and positive attitude and behavior than the other parents. It was determined that parents with very good past math achievement had higher expectations for "conceptual understanding and active participation" and "positive attitude and behavior". On the other hand, it is clear that the mathematical success perceived by the child's parents will have an effect on the behavior of the parents. A student who believes in learning mathematics through passive listening and memorizing rules can be more easily directed, if parent has a high expectation of active participation and conceptual learning. For that reason, educators should give importance to the family dimension that occurs outside the classroom.
