In order to establish groups and manage them effectively we utilize the 7 Steps of Data Analysis throughout the school year. We feel our students are ready to participate in our RTI rotation the second semester of kindergarten. This is mostly due to exposure and maturity. Below you will see the 3rd math assessment we use for screening purposes (pretest/post test). Since our groups are "fluid," this kind of screening confirms correct placement and adjustments are made as needed. Check out the assessment we are using this month (CCSS aligned):http://www.teacherspayteachers.com/Product/Math-Assessment-Numbers-to-30-1190082
These four photos show what our "enrichment" group worked on during RTI last week. Although money is not a kindergarten standard, skip counting is and that was the focus of this lesson (skip counting by 10s was the focus the previous week).
I should mention that notes go home for students in either "enrichment" group or "intervention" group. Both of these groups receive math homework that is leveled to meet their needs. Students that work below grade level, the "intervention" group, are expected to complete extra math homework over the weekend. We explain to the families that the classroom practice is not sufficient for their child and that additional practice time is essential.
