Math Intervention

Focus kindergarten through fifth-grade interventions on whole numbers. For kindergarten through grade five students, Tier two and Tier three interventions should focus almost exclusively on properties of whole numbers and operations. Some older students struggling with whole numbers and operations would also benefit from in-depth coverage of these topics.

Focus fourth- through eighth-grade interventions on rational numbers. Tier two and Tier three interventions in grades four through eight should focus on in-depth coverage of rational numbers and advanced topics in whole number arithmetic, such as long division.

Interventions at all grade levels should devote about ten minutes each session to building fluent retrieval of basic arithmetic facts.  Interventions on solving word problems should include instruction that helps students identify common underlying structures.

Guided practice should include immediate corrective feedback. Intervention materials should provide students opportunities to practice math concepts with visual representations such as
number lines, arrays, and strip diagrams. Interventionists should be proficient in the
use of visual representations. praise student effort and engagement. Include motivational strategies in Tier two and Tier three interventions, reinforcing students’ effort and attention to lessons and
rewarding accomplishments. Help students persist by setting goals and charting progress.

Tier two and Tier three math instruction should provide clear explanations with thinkalouds.  Explicit teaching includes guided practice with scaffolding of the required problem-solving steps.
