Place value is one of the underlying math skills that can make or break a student. Students NEED a solid understanding of place value to master skills such as addition, subtraction, mental math, and explaining how addition and subtraction work.
Why do student’s need to build place value knowledge?
A solid understanding of place value is fundamental to a student’s mathematical development, and it plays a crucial role in various aspects of their mathematical education. Here are several reasons why it’s important for students to have a solid knowledge of place value:
- Foundation for Arithmetic: Place value is the basis for our number system. It allows students to understand the meaning of digits in numbers and how they relate to one another. Without this foundation, students would struggle with basic arithmetic operations like addition, subtraction, multiplication, and division.
- Understanding Magnitude: Place value helps students understand the magnitude of numbers. It enables them to compare and order numbers, which is essential in real-world situations, such as determining which number is greater when comparing prices, measurements, or quantities.
- Decimals and Fractions: Place value understanding is crucial when working with decimal numbers and fractions. It enables students to comprehend the significance of the decimal point and the relationship between whole numbers and fractions, which are integral in various fields like science, finance, and engineering.
- Mental Math: Place value helps students develop mental math skills. When they understand the value of each digit in a number, they can more easily perform mental calculations and estimate results, which is useful in everyday life.
- Word Problems: Many word problems involve numbers with different place values. Without a solid understanding of place value, students may misinterpret the meaning of numbers in word problems and make errors in solving them.
- Base Systems: Place value is not limited to our base-10 (decimal) system. Understanding place value is essential for comprehending other base systems, like binary, hexadecimal, and octal, which are important in computer science and engineering.
- Mathematical Concepts: Place value is a building block for various mathematical concepts, including factors, multiples, prime numbers, and more. Without it, students may struggle to grasp these higher-level mathematical ideas.
- Problem-Solving and Critical Thinking: Learning place value encourages students to think critically and solve problems. They need to analyze numbers, break them down into their constituent parts, and make decisions based on their understanding of place value.
- Real-World Applications: Place value is essential in real-world situations, such as budgeting, understanding financial statements, cooking, measurements, and any scenario where numbers are involved. A strong grasp of place value is vital for practical life skills.
- Preparing for Advanced Mathematics: A solid understanding of place value is a prerequisite for advanced math courses, including algebra, geometry, and calculus. Without this foundational knowledge, students may struggle to progress in their mathematical education.
What does place value look like in Kindergarten through Second Grade?
In Kindergarten, place value practice primarily focuses on building a foundational understanding of our base-10 (decimal) number system. Kindergarteners begin to grasp the concept of place value, even though they may not use that specific terminology. The emphasis is on hands-on, visual, and concrete learning experiences. This can look like counting and number recognition, number decomposition, working with place value blocks or ten frames, and comparing numbers.
In first grade, place value practice builds upon the foundation laid in kindergarten. First-grade students delve deeper into understanding the place value system, focusing on the tens and ones places within two-digit numbers. This can look like completing mental math of 10 more and 10 less, using place value as a specific addition/subtraction strategy, working with place value blocks, using expanded form, comparing numbers, and using regrouping to solve addition and subtraction problems.
In Second Grade, place value practice becomes more advanced as students continue to build upon the foundational understanding of place value developed in earlier grades. Second Grade students work deeply with 2-digit and 3-digit numbers to solidify the knowledge they have previously built. This can look like addition and subtraction with regrouping, working with place value charts and grids, word problems, skip counting by 10s and 100s, and estimating.
The Secret to Place Value Success
It is critical that students are able to work fluidly and flexibly with base ten. One of the best ways for students to do this is to play games. Games will help students internalize place value knowledge allowing them to think flexibly and quickly.
One of my student’s favorite games is the Race to 1000 game.
Fun Fact: You can play Race to 100 by just using tens and ones, with the goal being to make 100 within 6 turns without going over! I started playing this game as a Second Grade teacher so that’s what I generally refer to it as Race to 1000!

How to Play Race to 1000 Place Value Game
To begin play, we divide into 2 teams. Each team gets a work mat and base ten materials while I collect the big foam die I have! (If you do not have any base ten materials, I have used these fun printable ones!) Regular sized dice work too, but the big foam one is fun!
The premise of the game is simple. Each team has 6 rolls to build a number that reaches as close to 1000 without going over! If they go over 1000, they lose.
When a team rolls, they look at the number and decide if they are adding ones, tens or hundreds to their number or work mat. After making the decision, they add to their work mat and play goes to the next team. Play continues until each team has made 6 rolls. Teams count their base ten materials and compare numbers! The team closest to 1000, without going over, wins! It’s a good idea to stop between rounds and have teams count their number so they know what their number is.
After students have played in a group for awhile, they love to play in partners. You can make copies of the work mat and either laminate or place in a page protector. Students can use dry erase markers to draw their place value representations or they can build with base ten manipulatives.
You can differentiate this game by changing the number that students build. Try going smaller or larger. Race to 100 would be a fantastic game for First Grade students using just tens and ones.
