Bridges in Mathematics Grade 2, Unit 5: Place Value to One Thousand
In this unit, your child works with numbers up to 1,000, learning that a three-digit number like 706 has hundreds, tens, and ones. They skip-count by 5s, 10s, and 100s; write numbers in words and in expanded form; and compare numbers with >, =, and <. This builds on the two-digit place value from earlier and sets up adding and subtracting with bigger numbers next.

What is my child learning in Unit 5?
- Seeing that the digits in 706 stand for 7 hundreds, 0 tens, and 6 ones, and that 10 tens make a hundred. Learn more: Hundreds, tens, and ones in numbers like 706
- Skip-counting by 5s, 10s, and 100s up to 1,000, including from a start like 47 that is not a round number. 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 to 1,000 as numerals, as number names, and in expanded form, like 400 + 30 + 6. Learn more: Reading and writing numbers to 1,000
- Comparing three-digit numbers by hundreds first, then tens, then ones, and writing 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
- Count by 10s together on a walk, starting from a number like 137: 147, 157, 167. Switch to 100s from 100 and see who reaches 1,000 first.
- Write down three-digit numbers from receipts or page numbers, and ask your child to say each one in hundreds, tens, and ones.
- Play a comparing game with cards: each of you draws three cards, makes the biggest number you can, and says which is greater using "greater than" or "less than."
Where kids can get stuck
- Writing 76 for seven hundred six, treating the zero in the tens place as nothing at all.
- Jumping from 199 to 1,000 instead of 200 when counting across a new hundred.
- Comparing from the ones place, deciding 298 beats 301 because 8 is more than 1.
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
- hundreds
- Groups of 100. In 706, the 7 means 7 hundreds, or 700.
- place value
- The value a digit has because of its spot in a number: ones, tens, or hundreds.
- digit
- One of the symbols 0 through 9 that we use to write numbers.
- expanded form
- A number written as the sum of its parts, like 400 + 30 + 6 for 436.
- number name
- A number written in words, like four hundred thirty-six.
- 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.
