Eureka Math Grade 2, Module 3: Place Value Counting and Comparison of Numbers to 1000
In this unit, your child counts and works with numbers to 1,000. They bundle 10 ones into a ten and 10 tens into a hundred, skip-count by 5s, 10s, and 100s, and write numbers in words and in expanded form. Then they compare numbers with >, =, and <. This place value thinking powers adding and subtracting within 200 next.

What is my child learning in Module 3?
- Bundling ones into tens and tens into hundreds, and seeing that 13 tens and 130 are the same amount. Learn more: Hundreds, tens, and ones in numbers like 706
- Counting within 1,000 by 1s, 10s, and 100s from any number, such as 47, 57, 67. Learn more about counting within 1,000: Counting within 1,000 · Learn more about skip-counting by 5s, 10s, and 100s
- Writing numbers to 1,000 in unit form, in words, and in expanded form, such as 6 hundreds 3 tens 2 ones and 600 + 30 + 2. Learn more: Reading and writing numbers to 1,000
- Comparing two three-digit numbers by hundreds, tens, and ones and writing >, =, 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
- Bundle straws, sticks, or crayons in groups of 10, then make a big number together and ask how many tens and how many hundreds it has.
- Count by 10s from an odd starting place on a walk, like 47, 57, 67, and switch to 100s each time you reach a corner.
- Write two house numbers or prices and ask your child which is greater, comparing the hundreds first and then the tens.
Where kids can get stuck
- Counting by 10s from 47 as 47, 50, 60 instead of 47, 57, 67.
- Being puzzled that 13 tens and 130 are the same amount.
- Leaving out a part with a zero beside it, writing 500 + 6 for 560.
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
- bundle
- A group of 10 things tied together to make one ten, or 10 tens to make a hundred.
- ones
- Single units. In 47, the 7 means 7 ones.
- tens
- Groups of 10. In 47, the 4 means 4 tens, or 40.
- hundreds
- Groups of 100. In 706, the 7 means 7 hundreds, or 700.
- unit form
- A number said by its places, like 6 hundreds 3 tens 2 ones for 632.
- expanded form
- A number written as the sum of its parts, like 400 + 30 + 6 for 436.
- skip-count
- Counting by a number other than one, like 5, 10, 15, 20.
- greater than
- More than. The symbol > means greater than, as in 52 > 25.
- less than
- Fewer than. The symbol < means less than, as in 25 < 52.
