Eureka Math² Grade 3, Module 1: Multiplication and Division Concepts
In this unit, your child starts the year with what multiplication and division mean, using equal groups and arrays. They work with the 2s, 5s, and 10s and then the 3s and 4s, switch factors around to find facts, and solve one- and two-step story problems. Place value with numbers up to 1,000 comes next.

What is my child learning in Module 1?
- Counting equal groups by skip counting, so 4 groups of 5 is 5, 10, 15, 20, written 4 × 5 = 20. Learn more: Multiplication as equal groups
- Sharing a total equally and finding the size of each share, such as 16 shared among 4 friends being 4 each. Learn more: Division as sharing into equal groups
- Drawing tape diagrams, bars split into equal parts, to show story problems about equal groups. Learn more: Multiplying and dividing in story problems
- Turning an array on its side to see that 2 × 6 and 6 × 2 have the same product, the answer in multiplication. Learn more: Shortcuts that make times tables easier
- Building quick recall of facts for 2, 3, 4, 5, and 10, and using each one to solve a related division. Learn more about knowing the times tables by heart: Knowing the times tables by heart · Learn more about dividing within 100
- Solving two-step problems, such as 5 boxes of 4 crayons plus 3 loose ones, and checking with an estimate. Learn more: Story problems with two steps
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
Hana has 3 plates with 5 strawberries on each plate. She writes 3 × 5. What does 3 × 5 tell her?
- How many strawberries there are in all
- How many strawberries are on each plate
- How many plates she has
How you can help
- Set the table and ask how many forks are needed if 4 people each get 2, then say it as 4 groups of 2, or 4 × 2 = 8.
- Deal out a deck of cards to 4 players during a game night and talk about how many each person got and why it came out even.
- Make up a story on a walk, such as 3 dogs with 4 legs each, and ask your child to draw it as a quick picture before solving it (12).
Where kids can get stuck
- Adding the two numbers instead of multiplying, so 4 groups of 5 becomes 9.
- Treating 20 ÷ 4 and 4 ÷ 20 as the same, writing the total in the wrong place.
- Doing the steps of a two-step problem in the wrong order, so the answer tells a different 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
- equal groups
- Groups that all hold the same amount, like 3 plates with 4 crackers each.
- array
- Objects arranged in equal rows and columns.
- multiply
- To join equal groups to find how many in all.
- divide
- To split a total into equal groups or equal shares.
- product
- The total you get by multiplying, like 12 in 3 × 4 = 12.
- quotient
- The number you get when you divide, like 5 in 20 ÷ 4 = 5.
- tape diagram
- A bar split into equal parts to show the numbers in a story problem.
- commutative property
- The rule that 3 × 5 and 5 × 3 give the same answer.
- skip count
- To count forward by 2s, 5s, 10s, or another number.
