Number Stax™ blocks are a fun, hands-on math tool where numbers don’t just sit on a page… they help students build math the way it’s meant to be learned—through physical exploration, seeing relationships, and discussion.
Built from soft, colorful, and durable foam, each block represents a number through its height, turning abstract ideas into something students can stack, compare, and truly see. Whether building a tower of 10 or breaking it into parts, learners experience math as a physical, creative act—not just a worksheet exercise.
Students love Number Stax -
• They feel like toys, not tools - stacking, building, and knocking down towers taps into natural play instincts—math sneaks in through the fun.
• Students instantly notice patterns and part-whole relationships: a “5” is taller than a “3,” and two “5s” match a “10.” It’s visual math magic.
• Creative freedom - from skyscrapers to stair-steps to number trains, every build tells a mathematical story.
Deep mathematical value -
• Number sense & counting: See quantities grow and compare sizes directly
• Operations: Physically model addition, subtraction, multiplication, and division
• Place Value: Understand teen numbers as a unit of ten and some ones
• Part-Whole Relationships: Compose and decompose numbers in a variety of ways
• Fractions & equivalence: Discover relationships by combining and comparing block lengths
• Early algebraic thinking: Explore equality, patterns, and unknowns concretely
Instead of memorizing, students construct meaning—one stack at a time!
