Sort and count
Sorting and counting is your child's first taste of working with information. Once groups are counted, your child can say which has more, the idea behind every chart and graph they will read later. In kindergarten they will put sorted groups in order by size, and by 1st and 2nd grade they will record counts in simple tables, picture graphs, and bar graphs and answer questions about them.
In this video, your child will learn to sort things and count each group.
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 purple crayons?
Example 2
How many crayons?
Your child's turn
How many cars?
The two key steps
- 1Put each kind in its own group.
- 2Count each group.
Mistakes to listen for
- Changing the sorting rule partway through, such as putting a blue truck with the cars because it is a vehicle.
- Counting the whole pile instead of each group, and giving one total instead of a number per group.
- Leaving out objects that do not seem to fit, so the group counts do not add up to the whole.

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 →
