🎥Video Lessons
💡 Video Tips:
⏸️ Pause after each large number and ask students to name the value of each digit (ten-thousands, thousands, hundreds, etc.).
👉 Have students point to the highest place value shown in the example (e.g., ten-thousands).
✍️ Ask students to rewrite the number in expanded form during pauses (e.g., 15,274 → 10,000 + 5,000 + 200 + 70 + 4).
🔁 Replay renaming examples and have students try a different representation (e.g., 157 hundreds).
💡 Key Ideas (Quick Guide)
- 🔢 Each digit has a place & value – (ten-thousands • thousands • hundreds • tens • ones)
- 📊 Large numbers can be renamed – 1 number can be represented in many ways (expanded form, renaming hundreds/tens, standard form).
- 👀 Read big numbers in groups of three – (ones • thousands • millions) — read from left → right.
- ✍️ Expanded form helps “see” the size – Break numbers into 10,000s, 1,000s, 100s, 10s, and 1s to understand what each digit represents.
