Creating tiered learning centers is a time-consuming process, yet, the results of these efforts are well worth the work in terms of student outcomes. Students' time on task, engagement, and achievement are all noticeably enhanced when students are provided with independent, leveled activities that address the standards in the geometry strand in mathematics. In this session, the presenter shares the process for creating tiered centers aligned with eight geometry standards as well as a set of complete centers for each standard that have been implemented successfully in a Grade 5 classroom.
