🔎 Teacher Notes: Goals, Success Criteria & Supports

"I can..." statements: I can add, subtract, and multiply decimals accurately and use estimation to check my answers.

Success criteria: Student lines up decimal points when computing, shows place-value reasoning, and uses an estimate to confirm the result.

Differentiation strategies: For students who need extra support, provide decimal grids or align numbers vertically, allow a calculator for checking only, and give one-step practice problems before multi-step ones.

Extension activities: Challenge advanced learners to solve problems with three-decimal-place multiplication or create real-world problems involving money and measurements that require multi-step decimal operations.

Dyslexia-friendly reading options: Provide a printed large-font copy, use high-contrast backgrounds, read problems aloud, and give one problem at a time with clear spacing.
