Mastery blocks (Math-U-See-style) Subtraction

How Mastery blocks (Math-U-See-style) teaches subtraction

Math-U-See treats subtraction as 'taking blocks away,' making the operation visible before it becomes abstract. A child builds a number with the integer blocks, removes the subtrahend bars, and reads the remaining blocks as the difference—no guesswork, no algorithms from memory. When regrouping is needed, the child physically trades a ten-bar for ten units, experiencing the 'borrowing' step as a concrete exchange rather than a pencil procedure. No new subtraction concept is introduced until the current one is solid. These free printable subtraction worksheets follow the block sequence from basic take-away through multi-digit regrouping, always paired with the build-write-say framework. The result is children who know why they borrow and can self-correct when a written answer doesn't match what the blocks would show.
