During classroom instruction, teachers often engage students in learning about a new topic or procedure by having them explore the mathematics that will be involved. Due to the large teacher-student ratio, the standard instructional cycle of demonstration, guided practice, corrective feedback, and review may be insufficient to help all students make progress toward expected outcomes. Furthermore, students having difficulty with mathematics require explicit and systematic instruction that includes modeling concepts, procedures, and proficient problem solving processes; verbalizing thought processes; guided practice; corrective feedback; and frequent cumulative review.
