Digi-Blocks are a teacher-tested, hands-on way to teach math, from Pre-K to Gr. 5+, for deep understanding. Based on an elegant nested design, all of the blocks pack into each other, only holding 10 blocks at a time and the "smart box" only closes when there are 10 blocks inside. This self-correcting feature eliminates the need to recount or trade. Not only can Digi-Block instill a profound understanding of number sense, it does it fast, elegantly modeling all four arithmetic operations through a place value-first approach.

Digi-Block is the only manipulative that grows with your students. Each increasingly sophisticated mathematical topic is elegantly modeled by Digi-Block's nested blocks. As your students move on to new concepts they always see the link to past topics.

More about Digi-Blocks 


Digi-Blocks are a fantastic resource for helping children to understand conceptually, and not merely procedurally, how our place value system works. Young students build understanding of the unitizing of ones into countable groups of ten. Unlike other materials, the ones can still be seen and manipulated to help those students who don't 'trust the count'; they can see the ones they have already counted within the blocks of ten and one hundred. 

For older students, the proportional growth of the packs of ten, hundred, and thousand lead to conversations about the ongoing relative proportion of how physically large quantities are as they get ten times larger; it is consistently a surprise to them how much space one million would take up as they are led to visualize how large ten thousand would be, how large one hundred thousand would be, and how large one million would be.  In this way, the studens conceptually understand that even though we only add one digit to the number, we are making the quantity so much larger. In a similar way, the decimal fractions set allows older students to actually see how much smaller one-tenth and one one-hundredth is.

For learning resource teachers working with older struggling students, using Digi-Blocks provide opportunities to experience sense-making with the very concepts students struggle with most: place value, multiplication, and decimal fractions. Having a set of Digi-Blocks should be a required manipulative for every school.

The Digi-Block System is thoroughly field tested. Studies show that using Digi-Block can improve your school's math program on three fronts:


Boost Student Understanding 

Improve Standardized Test Scores 

Quickly Get Up to Grade Level


Proven to be Significantly Better than Traditional Manipulatives

In order to test the effectiveness of Digi-Block, Digi-Block conducted a year long study in several 1st and 2nd grade classrooms. Classrooms were split into two groups: the Digi-Block Group, and the control group (which used traditional base-10 manipulatives). At the end of the year, both groups were given the same test. The results are shown below. 25% of Digi-Block students scored 100% on the test.
