The Mathematics Curriculum in Primary and Lower Secondary Grades

According to Act CXC of 2011 on National Public Education,4 the new national curriculum came into effect on September 1, 2013, implementing a spiral approach, for Grades 1, 5, and 9. TIMSS 2015 students were taught under the old national curriculum. Exhibits 2 and 3 present the main content objectives in the curricular framework5 for fourth and eighth grade mathematics pertaining to TIMSS 2015.
