Eureka Math² Grade 2, Module 4: Place Value Concepts to 1,000
In this unit, your child learns that a three-digit number is built from hundreds, tens, and ones. They count and skip-count to 1,000, write numbers as numerals, in words, and in expanded form, and compare them with >, =, and <. This builds on two-digit place value and prepares your child to add and subtract within 1,000 next.

What is my child learning in Module 4?
- Naming the value of each digit in numbers like 482, so the 4 means 4 hundreds, not 4. Learn more: Hundreds, tens, and ones in numbers like 706
- Skip-counting by 5s, 10s, and 100s within 1,000, crossing new hundreds smoothly, like 290, 300, 310. Learn more about counting within 1,000: Counting within 1,000 · Learn more about skip-counting by 5s, 10s, and 100s
- Reading and writing numbers like 315 as numerals, as number names, and in expanded form, 300 + 10 + 5. Learn more: Reading and writing numbers to 1,000
- Comparing three-digit numbers starting with the hundreds and showing the result with >, =, or <. Learn more: Comparing three-digit numbers with >, =, and <
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
How many hundreds are in 300?
- 3
- 30
- 300
How you can help
- Ask your child to read the number on a price tag or a book page and tell you what each digit is worth.
- Count by 5s or 10s together while waiting in line or walking, starting from a number like 285, and listen for the jump to the next hundred.
- Write a number for each of you, like 563 and 536, and ask who has more and why, before your child writes the symbol.
Where kids can get stuck
- Building 482 with 4 single blocks for the 4, treating it as four instead of four hundred.
- Writing 4 + 3 + 6 for 436 instead of 400 + 30 + 6.
- Skipping 20 when counting by 5s, as in 5, 10, 15, 25, because the endings feel alike.
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

- number name
- A number written in words, like four hundred thirty-six.
- numeral
- A number written with digits, like 436.
- skip-count
