Digi-Block FAQs


Yes. The Digi-Block method uses the same approach to mathematical pedagogy as the Common Core. Digi-Block covers the following Common Core standards: “Counting & Cardinality,” “Operations & Algebraic Thinking,” “Number & Operations in Base Ten,” and most of “The Number System.” Although we have not published a correlated list yet of each Digi-Block lesson matched with the corresponding Common Core Standard, Digi-Block lessons are fully aligned. Digi-Block is not a comprehensive curriculum. To fully cover all grade-level standards, one needs to supplement the other standards, most notably geometry and measurements and data, with other lessons. To teach number sense, operations, place value and decimals, etc., there’s nothing better than Digi-Block.


Yes! The schools with the best results use Digi-Block in every math class. Digi-Block can model all four arithmetic operations as well as more advanced concepts. See our About page for a list of videos.


The System is appropriate for any age student who is developing a sense of numbers. The Digi-Block System is currently being used in classes from Pre-Kindergarten through middle school. Digi-Block is effective over a wide range of student abilities.


Yes. The Digi-Block System is a supplemental program. It provides an effective approach for teaching number sense and basic operations. It does not require “additional time” but rather “alternative time.” Teaching with the blocks replaces how you would approach teaching the same concepts as suggested within the regular curriculum.


First, the Digi-Block System is the only mathematics manipulative that is conceptually pure – it is a truly representative model of our base ten number system. Ten single blocks back into holders creating a larger block-of-10. Ten blocks-of-10 pack to make a block-of-100. And again, ten blocks-of-100 build the block-of-1000. Because of the packing system there is no trading involved. Students naturally pack and unpack boxes, seamlessly performing all operations. Second, the size of the blocks show a precise relationship between the powers of ten; that is the block-of-10 is exactly ten times the size of the single block; the block-of-100 is exactly 100 times the size of the single block and ten times the size of the block-of-10. Lastly, Digi-Block is the ONLY math manipulative that can teach concepts as rudimentary as counting and as advanced as logarithms. Since Digi-Block is with your students every step of the way, your children will never miss the connections inbetween math concepts.
