“Whether we’re working on number sense, subitizing, or simple addition, Math Stackers® makes abstract concepts concrete.

We love watching our students light up as they physically manipulate the blocks and begin to truly understand math in a way that sticks.”

I love the visuals created by the size of the blocks, and having the videos in Math Stackers U to give me ideas on how to use them is amazing!

I love how students can manipulate the blocks to work out so many kinds of operations / arrays / multiplication / division / fractions / prime & composite numbers - literally we use them for all the standards we teach!

The inched sections on the sides of each Math Stacker open up possibilities for exploring measurement and fractions, not just basic facts, numbers, and operations.

I feel like every year decomposing numbers is a hard concept for some of my kiddos to grasp, but Math Stackers are a game changer for this concept!

Tiffany F.

Teacher and student interacting with Math Stackers in a classroom setting

I have been so impressed with how students can learn number order just by making stairs with their Math Stackers. It lets them picture the numbers as something more than just a numeral.

I love how the grooves show 1 unit on each Math Stacker, they make it easy to see each number as a whole made up of equal parts.

We Get These Questions All The Time...

What is a Math Stackers® Learning System, and how is it different from other math manipulatives?

A Math Stackers® Learning System is a complete, hands-on math resource designed for discovery-based learning from Pre-K through 5th grade. It includes 96 high-density foam Math Stackers®, leveled teacher resources, and access to Math Stackers® U, our online library with training videos, activity ideas, and printable station cards.

Math Stackers® are purposefully designed to help students visualize and model math concepts:

The height of each block represents its numeric value, building visual understanding.
Notched sides allow students to feel the value and practice one-to-one correspondence.
The back of each block is blank, creating opportunities for proportional and fraction reasoning.
Our logo on the bottom ensures blocks are stacked correctly, keeping numbers visible.

Each system also comes with a free storage hamper, our gift to help you get organized and started right away. Math Stackers® is more than just a set of manipulatives—it’s a complete system designed to help students model, test, and prove their math thinking.

– Jennifer I, Coordinator of Early Math Intervention, TX

"My kids are HARD on our Math Stackers and they are holding up! The foam material is great for physical manipulation but being quiet when they topple. Also, the logo on the bottom to help students learn appropriate number positioning as well as the notches on the sides to help us count and associate the value and the numeral."

– Maria T, SPED Teacher, Bridgewater, VA

"At first, I thought Math Stackers were just for number sense, but after seeing how they could be used to problem solve upper grade level word problems, I'm hooked!"

– Ashley S, 5th Grade Teacher, Kansas City, MO
