Catherine Roberts and Jennifer Clark discuss their shift in teaching approaches in middle school math due to a whole class model failing to engage diverse student needs, including reluctant learners and those with learning disabilities. They introduce the T.I.M.E. acronym representing different station types in their classroom, which includes teacher-led instruction, independent tasks, math facts practice, and essential reviews. The assessment methods, including weekly quizzes and flexible learning groups, are utilized to adapt instruction based on student performance.
