Compare numbers up to a million
Comparing big numbers gives your child a reliable way to answer "which is bigger?", a question that comes up everywhere. It helps with rounding this year, and in 5th grade, comparing decimals like 0.45 and 0.5 uses the same place-by-place check from the left. You’ll see it all around: in sports crowds, in prices, and in which of two drives is longer.
In this video, your child will learn to compare numbers up to a million.
The lesson stops at each question for your child's answer.
Three problems, each a little harder
Each problem is worked step by step. Your child will solve the last one before Bobby shows how.
Example 1
9,850 ? 10,200
Example 2
60,215 ? 60,158
Your child's turn
384,207 ? 384,270
The three key steps
- 1Line up the places.
- 2Compare from the greatest place.
- 3First different place decides.
Mistakes to listen for
- Judging by the first digit alone, so 9,850 seems greater than 12,400 even though it has fewer digits.
- Comparing from the right instead of the left, deciding 45,719 is greater than 46,108 because 9 is bigger than 8.
- Calling two numbers equal because they use the same digits, such as 52,301 and 52,310.

What happens when my child answers a question?
A right answer gets a cheer, and the lesson carries on. If your child isn't sure, they can tap "I don't know yet", and Bobby gives the answer and shows another example. Nothing is scored or stored.
Is this the same lesson that's on YouTube?
Yes. Here, the lesson stops at each question and waits for your child to answer. On YouTube, each question stays on screen for a few seconds, and then the lesson plays on.
