Place value → 1,000,000
1. Hook
- Hear the goal. Watch one worked example (pictures + steps).
- Try the interactive lab on this page. Move something. Read what happened.
- Guided fills, then independent practice, then the scored quiz.
- Teach it back: one example + the usual mistake.
There is no classroom teacher. This page teaches you. The lab is on this site — not an outside classroom. Stay on this page. The pictures, the game, and Your work are the lesson.
A million is a thousand thousands! How do you read, write, and compare numbers that big?
Then: lab → guided → quiz → teach it back. The lab is the lesson, not a decoration.
2. Teach

Standards alignment: CCSS.MATH.CONTENT.4.NBT (domain-level; works with any state’s standards)
STEM this week is Place value → 1,000,000: write the number, label the unit, check a second way.
- Each place is 10 times the place to its right: ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions.
- Forms: standard (482,316), word (four hundred eighty-two thousand, three hundred sixteen), expanded (400,000 + 80,000 + 2,000 + 300 + 10 + 6).
- Compare from the greatest place: 482,316 vs 479,999: hundred thousands same, ten thousands 8 > 7, so 482,316 > 479,999.
Commas separate periods (groups of 3): 1,000,000.
The 4 in 40,000 is 10 times the 4 in 4,000.
- Number: 305,072.
- 3 hundred thousands.
- 0 ten thousands, 5 thousands.
- 0 hundreds, 7 tens, 2 ones.
- Expanded: 300,000 + 5,000 + 70 + 2.
Write 5 big numbers from news or sports in standard, word, and expanded form, then order them.
Forgetting zeros as placeholders (writing 30572 for 305,072).
City populations and stadium crowds use big numbers.
No classroom teacher today — this page is the lesson. A grown-up sits nearby. Model once, wait 10–20 seconds, then prompt. A grown-up sits nearby. Model once, wait, then let the child try.
