🧭 Teacher Notes & Supports

I can: I can identify the value of digits in whole numbers and write numbers in expanded form.

Success criteria: I can point to a digit, name its place (ones, tens, hundreds, thousands, etc.), give its value, and write a number as a sum of place values.

Differentiation strategies: Use place-value charts and base-ten blocks for students who need support; read questions aloud and provide one-on-one modeling; give shorter prompts as needed.

Extension activities: Convert numbers between standard, expanded, and word forms up to 7 digits; have advanced learners create their own 5- or 6-digit numbers and explain each digit's value.

Dyslexia-friendly options: Provide a version with larger spacing and a sans-serif font, allow colored overlays, read items aloud, and allow extra time for reading and responses.
