Sort into groups and count
Sorting toys or snacks and counting each pile is how your child begins working with data. It leads to 1st grade, where they organize information into simple charts and say how many more are in one group, and to 2nd grade, where they make picture graphs and bar graphs. Reading graphs carefully is a skill they will use later in science, in the news, and in many everyday decisions.
In this video, your child will learn to sort things, count, and find the most.
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
How many cars?
Example 2
Which group has the most?
Your child's turn
Which group has the most?
The three key steps
- 1Put each kind in its own group.
- 2Count each group.
- 3The greatest number has the most.
Mistakes to listen for
- Ordering the groups by the space they take up, so 5 large blocks seem like more than 8 small ones.
- Putting the groups in order from fewest to most when asked for most to fewest.
- Sorting by their own rule, such as grouping toy animals by size when asked to sort by whether they fly.

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 sorting things into groups and counting them, 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.
Where can I learn more?
There's a short, kid-friendly lesson like this one for every Pre-K to 5th grade math skill, all in our video library. Our parent's guide to sorting things into groups and counting them has more on where kids get stuck and how you can help at home. In the club, your child practices at just the right level, about five minutes a day, and you get parent-friendly reports as they grow. Learn more about how it works →
