Solve problems with fraction line plots
Line plots give your child's fraction arithmetic a real job, like finding total rainfall or the difference between two measurements, and they build comfort reading a ruler to the eighth of an inch. They lead into the data displays of 6th grade, where your child will describe a set of numbers with ideas like the average and the middle value, and into science, where measurements are rarely whole numbers.
In this video, your child will learn to solve line plot problems with fractions.
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
We use two thirds of the heaviest basket. How many pounds is that? It is ?/4 pounds.
Example 2
24/8 cup shared equally among 6 beakers. Each beaker gets ?/8 cup.
Your child's turn
If the water were shared equally, how much would each jug have? ?/4 gallons
The three key steps
- 1Multiply for a fraction of it.
- 2Add, then divide to share.
- 3Share: the bottom number stays.
Mistakes to listen for
- Spacing the fraction marks unevenly, so 1/8 and 1/4 end up as far apart as 1/4 and 1/2.
- Counting the Xs when asked for a total, saying six days of rain made 6 inches instead of adding to 1 3/4 inches.
- Placing 3/8 in the wrong spot, often after 1/2, because they are unsure it falls between 1/4 and 1/2.

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 measurement charts with halves, quarters, and eighths, 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 measurement charts with halves, quarters, and eighths has more on where kids get stuck and how you can help at home.
