Eureka Math² Grade 3, Module 3: Multiplication and Division with Units of 0, 1, 6–9, and Multiples of 10
In this unit, your child learns the facts for 6, 7, 8, and 9, plus the rules for 0 and 1, completing the times table. They use facts they know to build new ones, find missing numbers, spot patterns, and multiply by multiples of 10 like 8 × 30. Next, these facts help find area, the space a shape covers.

What is my child learning in Module 3?
- Solving story problems with the 6s through 9s, such as 63 stickers shared on 9 pages, by drawing and writing an equation. Learn more: Multiplying and dividing in story problems
- Finding the missing number in sentences like ? × 7 = 42, using a known fact to work backward. Learn more: Finding the missing number, like 7 x ? = 56
- Using the associative property, regrouping three factors, to see 3 × 2 × 4 as 6 × 4 or 3 × 8. Learn more: Shortcuts that make times tables easier
- Practicing facts like 6 × 8 and 9 × 7 until they come quickly, and knowing 0 times any number is 0. 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 with the newer facts, like 4 packs of 7 cards with 6 given away, and checking with an estimate. Learn more: Story problems with two steps
- Explaining why a pattern happens, like each product in the 6s being double the matching product in the 3s. Learn more: Spotting patterns in times tables
- Multiplying a one-digit number by tens, like 8 × 30 = 240, by thinking of 8 groups of 3 tens. Learn more: Multiplying by tens, like 4 x 70
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
Ravi finds 16 socks in the laundry. He puts them into pairs, with 2 socks in each pair. How many pairs does he make?
- 8
- 32
- 14
How you can help
- Choose one set of facts for the week, such as the 8s, and spot them around you, like 3 spiders in a picture book having 3 × 8 = 24 legs.
- Ask your child to double a 3s fact to find a 6s fact, such as 3 × 7 = 21 so 6 × 7 = 42, while you wait in line.
- Ask how many minutes are in 4 half hours of playtime, using 4 × 30 = 120, and talk about how knowing 4 × 3 = 12 helped.
Where kids can get stuck
- Mixing up facts that sound alike, such as 6 × 8 and 6 × 7, and answering 42 for both.
- Thinking 0 × 9 equals 9, mixing up the rule for 0 with the rule for 1.
- Writing 8 × 30 = 24, multiplying the digits but forgetting the tens.
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
- associative property
- The rule that (2 × 3) × 4 and 2 × (3 × 4) give the same answer.
- factor
- One of the numbers you multiply, like 4 and 6 in 4 × 6.
- product
- The number you get when you multiply two factors.
- unknown
- A missing number in a problem that we need to work out.
- multiple of 10
- A number like 20, 50, or 90 that is made of tens and no ones.
- pattern
- Something that repeats or changes by a rule we can describe.
- double
- Twice as many; double 7 is 14.
- fluently
- Quickly and correctly, without counting on fingers.
