Whole Number Place Value Disks, Ones to Millions

Turn place value into something students can hold, represent, and reason about!

These non-proportional disks keep the focus on the value of digits helping students truly grasp how place value works. Regrouping becomes visible and intuitive as learners physically trade ten of one value for one of the next.

Perfect for:
• building numbers in expanded form
• comparing and rounding
• modeling all four operations concretely


These disks smoothly bridge concrete to pictorial to abstract. From ones to millions, they make complex yet critical concepts feel manageable, clear, and confidence-building.

This 126-piece set includes 18 foam disks for each value from 1 all the way to 1,000,000, with every place value in its own bold color, making patterns and structure pop instantly.
