Suddenly, math becomes something you can hold on to.
With these MAB blocks (Dienes Material), children make the decimal system visible and tangible. Units, tens, hundreds, and thousands no longer become separate concepts, but concrete building blocks. By building, stacking, and combining, a real understanding of place value and number structure develops.
This decimal math set is ideal for children aged 6 and up who benefit from visual and tactile support. The material helps them understand addition, subtraction, multiplication, and division—not through tricks, but through understanding.

The units, tens, and hundreds can be linked together. This literally visualizes the bundling principle of the decimal system:
10 units = 1 ten
10 tens = 1 hundred
10 hundreds = 1 thousand

What this calculation material strengthens
- Insight into place value (E – T – H – D)
- Understanding of number structure such as 734 = 7H 3T 4E
- Recognize and utilize structure in numbers
- Comparing quantities and "content" by building
- Collaborate and work independently

For many children—especially in grades 3, 4, and 5—concrete math materials make the difference between applying tricks and truly understanding them. This Dienes material supports math comprehension and is ideal for extended instruction, remedial teaching, or extra practice at home.

Note: For larger sums (e.g., 75 + 50), more tens are sometimes needed than are present in a single set. For more complex exercises, it is therefore helpful to combine two sets.

Sustainable and future-oriented
This decimal calculator is made of 100% recycled plastic (post-consumer) and is fully recyclable. A conscious choice for daily use in the classroom or at work.

Math doesn't have to remain abstract. With this material, children literally build their understanding—and that foundation remains strong.
