Eureka Math² Grade 3, Module 5: Fraction Concepts
In this unit, your child learns what fractions are and how they work. They split shapes into equal parts, name fractions like 2/3 and 5/6, place them on a number line, and compare fractions by the size of their parts. Whole numbers show up as fractions too, like 4/4 = 1. Next comes a unit on shapes, measuring, and data.

What is my child learning in Module 5?
- Naming fractions with unit fractions, so 5/6 is 5 parts of size 1/6, using paper strips and pictures. Learn more: What a fraction like 3/4 means
- Placing fractions on a number line and seeing that 4/4 and 1 land on the same point. Learn more: Fractions on a number line
- Comparing fractions like 2/3 and 2/5 by reasoning that thirds are bigger pieces than fifths. Learn more about finding equal fractions, like 1/2 = 2/4: Finding equal fractions, like 1/2 = 2/4 · Learn more about comparing fractions by size
- Splitting shapes into equal parts and checking that each part covers the same area, even when the parts look different. Learn more: Splitting shapes into equal parts
Sample questions to try together
These are real questions from our practice. Tap the speaker to hear one read aloud, or the light bulb for a hint, and talk about the answer together.
Question 1 of 3
Tariq is painting this paper strip blue for a class banner. So far he has painted the blue parts. What fraction of the strip does he still need to paint?
- 5/3
- 3/8
- 5/8
How you can help
- Fold a tortilla or napkin in half, then in half again, and ask your child to name each part and compare 1/2 with 1/4.
- Use a ruler to find 1/2 inch and 1/4 inch, showing that fractions are points along a length, just like whole numbers.
- Ask whether your child would rather have 2/3 or 2/5 of the same pizza, and listen to how they decide.
Where kids can get stuck
- Thinking the bigger denominator always means the bigger fraction, so 2/5 seems greater than 2/3.
- Counting 5 marks from 0 to 1 and calling the parts fifths, when the 4 spaces make fourths.
- Splitting a shape into parts of different sizes and still naming each part as a fraction of the whole.
Practice makes perfect
Bobby's Math Club has practice problems that adapt to your child’s level, each with a detailed explanation and an easy-to-follow video, so your child can build confidence in these skills one step at a time.
Words your child will hear
- fraction
- A number that shows part of a whole or part of a group.
- unit fraction
- A fraction with 1 on top, like 1/4, that names one equal part.
- numerator
- The top number in a fraction, counting the parts we are talking about.
- denominator
- The bottom number in a fraction, naming how many equal parts the whole has.
- number line
- A straight line marked with numbers in order, with equal spaces between them.
- equivalent fractions
- Different fractions that cover the same amount of the whole.
- compare
- To decide which number is greater, less, or if they are equal.
- equal area
- Parts that cover the same amount of space, even if they look different.
