Eureka Math² Grade 4, Module 3: Multiplication and Division Word Problems
In this unit, your child applies multiplication and division to word problems. They solve "times as many" comparisons, multi-step stories, and problems about the area and perimeter of rectangles, often drawing a tape diagram first. It puts last unit's place value strategies to work, and leads into fractions and equivalence.

What is my child learning in Module 3?
- Solving comparison problems in both directions, like finding a number 6 times as large or finding what 48 is 6 times. Learn more: Story problems about "times as many"
- Solving multi-step word problems with tape diagrams, writing equations with a letter for the unknown, and interpreting remainders. Learn more: Multi-step story problems and leftovers
- Solving area and perimeter problems, like finding a garden's length when its area and width are known. Learn more: Using area and perimeter to solve real problems
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
Amara's dad planted 3 times as many bean seeds as Amara. Amara planted 12 seeds. How many seeds did her dad plant?
- 15
- 4
- 36
How you can help
- Reverse a comparison at dinner. Say you walked 12 blocks, which is 4 times as far as your child walked, and ask how far they walked and why it takes dividing.
- Sketch two bars on a napkin, one short and one 5 short bars long. Let your child invent a story to match, using real numbers and their own toys or snacks.
- Plan a pretend patio of 54 square feet that is 6 feet wide. Ask your child how long it is, then how much edging goes around it.
Where kids can get stuck
- Multiplying every time they read "times," so "40 is 5 times as many as what?" gets 200 instead of 8.
- Drawing the bar model backwards, with the larger amount as one bar, which points to the wrong operation.
- Giving "5 R5 vans" as an answer, without deciding what the leftover people mean in the story.
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
- multiplicative comparison
- Comparing two amounts by multiplying, as in "15 is 3 times as many as 5."
- additive comparison
- Comparing two amounts by adding or subtracting, as in "15 is 10 more than 5."
- tape diagram
- A drawing of bars that shows how the amounts in a story problem compare.
- unknown
- The missing number in a problem, often shown with a letter or a box.
- variable
- A letter that stands for an unknown number in an equation.
- remainder
- The amount left over when a number can't be split into equal groups exactly.
- area
- The space inside a flat shape, measured in square units.
- perimeter
- The distance all the way around a flat shape.
