Place Value Game
Play a free place value game built around real base-ten blocks, not a text quiz. Build the Number has you place block columns to match a target number; What's the Value? highlights a digit and asks what it stands for; Expanded Form has you build a number's expanded form one place at a time. Three levels move from 0–99 up to 0–9,999, with no sign-up and nothing saved.
This free place value game's core interaction is genuine base-ten blocks: ones, tens, hundreds, and thousands columns you build with +/− controls, not a single multiple-choice question. What's the Value? and Expanded Form add two more angles on the same digits, and every mode always agrees exactly with the number shown.
Place base-ten blocks in each column to build the target number.
Not a test — nothing is saved after you leave.

How to use the place value game
- 1Choose Build the Number, What's the Value?, or Expanded Form, and a level.

When this is useful
Understanding base-ten place value
Build real number sense by placing ones, tens, hundreds, and thousands blocks by hand.
Reading digit value in context
Practice recognizing that a digit's value depends on its place, not just the digit itself.
Writing expanded form
Practice breaking a number into its place-value parts, like 3,482 = 3,000 + 400 + 80 + 2.
Classroom place value warm-ups
Put a Build the Number round on the projector for a quick whole-class warm-up.
Progressive difficulty
Start with two-digit numbers and work up to four-digit numbers as students get comfortable.
Examples to try
Level 1: 0–99
Tens and ones only — a gentle starting point for two-digit numbers.
Level 2: 0–999
Adds hundreds, for three-digit numbers.
Level 3: 0–9,999
The full set of columns, for four-digit numbers.
Tips for better results
Start with Build the Number
Physically placing blocks in each column builds the foundation the other two modes rely on.
Watch for place-value mix-ups
What's the Value? is designed around the exact mix-up students make most, like reading the 7 in 700 as 7.
Save Expanded Form for last
Writing a number as a sum of its place values combines every place at once, so it's the most complete check.
Move up a level once a number feels easy
Progressing from two-digit to four-digit numbers keeps the challenge matched to what a student can already do.
How the place value game works
Every number in this game is built from exact base-ten digits, extracted with integer division and remainder, never a string or decimal parse, so the blocks shown and the numeric answer always agree exactly.
Build the Number gives you a target and empty columns; add blocks with +/− controls until each column's block count matches that column's digit. What's the Value? highlights one digit with its own blocks shown and asks for its value. Expanded Form asks you to choose the correct value for every place at once.
Each level changes only how many columns are in play — ones and tens, then hundreds, then thousands — so the same blocks and controls are used throughout, just with one more column added at a time.

Frequently asked questions
Is this place value game free?
Yes, completely free, with no account and no limit on how many rounds you play. There are no ads.
What's the difference between the three modes?
Build the Number gives you a target number and empty columns to fill with blocks. What's the Value? highlights a digit and asks what it's worth. Expanded Form asks you to choose the correct value for every place at once.
Are the base-ten blocks accurate?
Yes. Each column's block count always matches that column's real digit, and every check compares exact digits, never an approximation.
What levels are available?
Level 1 covers 0–99 with tens and ones. Level 2 adds hundreds, for 0–999. Level 3 adds thousands, for 0–9,999.
Does this use AI?
No. This is a browser-only game with exact integer place-value arithmetic. It does not use AI, and the game runs on your device.
Is it good for early place value practice?
Yes. Level 1's two-digit numbers suit early learners, while Level 3's four-digit numbers suit students ready for a bigger challenge.
Does the game work well on a tablet or phone?
Yes. Block columns wrap to fit narrower screens, and every control is a large tap target.
Are scores saved?
No. Your score, streak, and session best stay in your browser for the current session and are cleared when you leave the page.
