These color-coded place value cards help students visualize numerical concepts and build number sense. The set supports instruction in expanded form, comparisons (greater than/less than), addition and subtraction without regrouping, multiplication, and other foundational math skills. The color system aligns with Sensational Math Place Value Discs for consistent reinforcement. Each card measures 4" in height, with lengths varying from 2-1/2" to 17-1/2" to represent different place values. The set includes 10 cards each for ones, tens, hundreds, thousands, ten thousands, hundred thousands, and millions—70 cards total. Designed for grades 1–6, the cards come in a resealable poly bag for easy storage.
