Inkgrad turns math practice into a simple paper loop: print a worksheet, let your child solve it with a pencil, photograph the finished page β€” and get it graded in seconds. No screens for the child. No answer keys for you to check. Just focused, one-page practice that adapts to what your child actually gets wrong. HOW IT WORKS β€’ Set a goal β€” tell Inkgrad about your child in a sentence and pick from suggested topics and a target grade. β€’ Tap Next β€” a one-page worksheet is generated to move them toward that goal, informed by everything they've solved before. β€’ Print it (or share the PDF) and hand over a pencil. β€’ Photograph the completed page β€” Inkgrad reads the QR code, checks every answer, and grades it automatically. β€’ Watch mastery grow β€” per-topic scores show what's solid and what needs another pass, and worksheets adjust accordingly. BUILT FOR FAMILIES β€’ Multiple children per account, each with their own goals, worksheets, and progress. β€’ Grades 1–12, plus advanced college-level topics for kids who are ahead. β€’ Optional curriculum focus (Common Core, California, New York, Texas) to guide topic selection. β€’ Upload several pages at once β€” multi-page PDFs are split and graded per page, per child. WHY PAPER? Writing by hand is still how math sticks. Inkgrad keeps the practice on paper where it belongs and moves everything else β€” choosing the right problems, checking the answers, tracking progress β€” off your plate. Start free: every account includes a monthly allowance of worksheets. End User Agreement: https://inkgrad.com/agreement
