Each number is one more
Seeing that each next number is one more is your child's first step toward adding. It lets them answer "seven and one more" by saying eight, without recounting, and it leads to counting on in kindergarten and 1st grade: to find 8 + 3, start at 8 and count three more. Later it helps with number lines, where every step to the right is one bigger.
In this video, your child will learn to see that each number is one more.
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
What number is one more than 2?
Example 2
What number is one more than 5?
Your child's turn
What number is one more than 7?
The three key steps
- 1Count the dots.
- 2Add one more dot.
- 3The next number tells how many.
Mistakes to listen for
- Recounting the whole group from one after a single object is added, instead of saying the next number.
- Guessing that one more than five is seven, instead of moving to the very next number.
- Thinking that taking one away changes the total by a lot, and not yet knowing one less than four is three.

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 each number in the count is one more, 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.
