ABOUT THIS GAME
What does Tens & Ones Builder practice?
Each round gives students a target two-digit number to build with
tens rods and ones cubes. Children add and remove base-ten blocks
until the model matches the number, helping them see how tens and
ones work together to create place value.

in a two-digit number.
🧱Tens & Ones
Connect tens rods and ones cubes with the tens and ones
digits in a number.
➕Number Decomposition

from its parts.

numbers up to 99.
