EXT: Compare numbers (billions)

Lesson

When we compare numbers, to see which is bigger or smaller, we can use the same method, no matter how big the number. We know $234$234 is bigger than $134$134, because $200$200 is bigger than $100$100, so let's use that same approach to work on billions.

Place value is our friend here, and comparing numbers in the same place value column is how we tackle these problems.

This video has some huge numbers to compare, but you'll see place value saves the day!
