Yesterday we learned monarchs fly up to 3,000 miles. But what does a number that big actually mean? Mathematicians make big numbers make sense by breaking them into pieces.
Numbers grow in a pattern! Ten ones make a ten. Ten tens make a hundred. Look how each one is built from the one before:
Can you count the little squares in the big one?
Let’s talk
How many little squares are in the long blue bar? Let’s count them!
How many blue bars would you need to fill the big green square?
Do you think there are more than 100 students in our whole school?

The blue bar has 10 little squares. You’d need 10 bars to fill the green square — that makes 100! And here’s a big-number fact: counting out loud to 1,000 would take about 15 minutes.
Try it
Count by tens! Let’s go together: 10, 20, 30, 40… all the way to 100. Now hold up ten fingers — that’s one “ten bar” on your hands!
Big numbers only feel real when you connect them to something you can picture. Let’s take the monarch’s 3,000 miles apart.
Three ways to understand one number.
Let’s talk
If a monarch flies about 50 miles a day, roughly how many days does 3,000 miles take? Estimate first.
Chattanooga to Los Angeles is about 2,000 miles. So 3,000 miles is about how many times that trip?
In 3,000, why do we write three zeros? What job is each zero doing?
Reveal the answersHide the answers
3,000 ÷ 50 = 60 days — about two months of flying. 3,000 ÷ 2,000 = 1.5, so it’s like flying to Los Angeles and then halfway back. And the zeros are placeholders: they show there are no hundreds, no tens, and no ones — exactly the job the Maya invented zero to do!
Try it
Make it real! With a partner, come up with your own way to explain how far 3,000 miles is — using something you actually know. Trips around a track? Drives to a city you’ve been to? The best explanation makes the number feel true.
