he first time students log into Think Through Math, they take an adaptive placement test. The test includes a maximum of 25 items that sample students’ math knowledge. The placement activity creates a personalized learning pathway for each student that targets grade-level expectations. The placement begins with an item that is 2 grade levels below the student’s grade level. The assessment searches for the grade level at which students consistently demonstrate mastery. Once that is determined, the adaptive exam ends and the performance level of the student is set at the highest grade level where the student was successful with the items presented. This data establishes the depth of a scaffold where precursor lessons are inserted between the student’s performance grade level and their actual grade level.
