How can you tell they’ve got it: Working with Large Numbers?

If they’ve got it, you’ll see things like: What is the largest six-digit number with digits summing to 15?; A stadium holds 67,450 people. Round to the nearest thousand for a news report; Order the populations of five cities and find the difference between the largest and smallest. Or just try it together: If your child is told the population of a city is 2,347,819, can they read that number aloud correctly and say roughly how many millions it is?
