Add numbers up to a million
Adding big numbers with ease frees your child to think about what a longer problem is asking, instead of getting stuck on the arithmetic. These sums sit inside much of what comes next: multi-step story problems, measurement, and area and perimeter. In 5th grade, the same lining up of places is how your child adds decimals, such as 12.5 + 3.75. And at home, it is how you total a receipt or a road trip.
In this video, your child will learn to add 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
3,425 + 2,341 = ?
Example 2
4,526 + 2,739 = ?
Your child's turn
247,856 + 68,379 = ?
The three key steps
- 1Line up the places.
- 2Add each place, ones first.
- 3Ten or more? Carry the new ten.
Mistakes to listen for
- Lining numbers up by their left edges instead of by place, so 2,375 + 418 comes out as 6,555 instead of 2,793.
- Forgetting to add a regrouped ten, so 4,568 + 1,375 comes out as 5,933 instead of 5,943.
- Writing each column’s whole total instead of regrouping, so 658 + 275 becomes 81,213 instead of 933.

Questions parents ask
Does my child need an account to watch?
No. You can watch this on any device at any time. If your child would like to practice adding numbers up to a million, and you'd like parent-friendly reports on your child's progress and growth, you can join Bobby's Math Club for unlimited free practice.
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.
