Hello future math whizzes! We're thrilled to provide you with a fantastic printable worksheet designed to help your 2nd graders master place value up to 1000. This activity is structured to be engaging and comprehensive, covering key concepts, vocabulary, and encouraging critical thinking. It’s perfect for in-class work or as a take-home assignment. Let’s dive in!
Topic Summary: Understanding Place Value Up to 1000
Place value is a super important idea in math! It helps us understand the true worth of each digit (number symbol) in a larger number. In second grade, we often work with numbers up to 1000, which means we’ll be looking at the ones place, the tens place, and the hundreds place. Think of it like a team: each digit has a special job based on where it stands!
For example, in the number $472$:
- The $2$ is in the ones place. Its value is $2 imes 1 = 2$.
- The $7$ is in the tens place. Its value is $7 imes 10 = 70$.
- The $4$ is in the hundreds place. Its value is $4 imes 100 = 400$.
When you put these values together, you get $400 + 70 + 2 = 472$. Each place is 10 times bigger than the place to its right! This understanding helps us read, write, compare, and work with bigger numbers easily. Let's practice!

Part B: Fill in the Blanks!
Read the paragraph below and fill in the missing words using the word bank provided.
Word Bank: tens • hundreds • value • ones • expanded
In the number $562$, the $5$ is in the _______ place, meaning it has a _______ of $500$. The $6$ is in the _______ place, representing $60$. Finally, the $2$ is in the _______ place, which is simply $2$. We can write $562$ in _______ form as $500 + 60 + 2$. Understanding place value helps us to know the real worth of each part of a number!
Your Answers:
- In the number $562$, the $5$ is in the place, meaning it has a of $500$.
- The $6$ is in the place, representing $60$.
- Finally, the $2$ is in the place, which is simply $2$.
- We can write $562$ in form as $500 + 60 + 2$.
