Teach, Assess, Reteach
Check every answer and require students to explain at least one method. Record independent, guided, or reteach. Verify understanding with new numbers rather than repeating an answer the student memorized. Accelerate by prerequisite mastery, not age. This is only the first unit of the grade’s mathematics program.
Grade 2 Mathematics | Five-Day Extension Teacher Guide
Read the associated student worked example, model the first step, and require independent explanations. Record correct answers, evidence of understanding, and whether prompting was needed.

Formative Assessment and Reteaching
Score the four independent Day 5 problems and look for patterns in errors. A missed concept requires a concrete model, guided example, and a new independent problem before advancing. Keep student work private. This unit is a building block, not proof of whole-grade mastery.
