Grades K-6: Formative Assessment and Differentiated Instruction Math Formative Assessment and Differentiated Instruction A variety of resources for formative assessment keeps kids on track: Show What You Know provides diagnostic assessment of prerequisite skills at the beginning of every chapter. Student responses to leveled items provide formative assessment for teachers to support learning gaps immediately before teaching new concepts. Teachers have a wide array of resources to support Tier 2 and Tier 3 Intervention, EL’s, and students who need a challenge. Share and Show is featured in every lesson, so formative assessment is ongoing and easy to manage. Teachers can provide “on-the-spot” feedback and remediation to students who have misconceptions. Personal Math Trainer provides instruction adapted to each student's needs, and provides teachers further data on student growth and gaps. Back More Knewton™ is a trademark of Knewton, Inc.
