MathBoard is a handwriting-first mental-math practice app. Generate arithmetic worksheets, solve each problem by hand on an iPad whiteboard, and get instant auto-grading, wrong-answer explanations, and printable PDFs. Pick a ready-made set or build your own: ① Within-10 / within-20 / within-50 / within-100 addition and subtraction ② Two-digit addition and subtraction ③ Multiplication tables, division tables, and mixed × ÷ ④ Compare numbers (greater than, less than, equal to) ⑤ Four operations mixed Work each problem with Apple Pencil or a finger on a per-question whiteboard — line up column working, carry and borrow, draw it out. MathBoard grades instantly, tracks accuracy and time, and saves every wrong answer with the correct solution, your draft, and a step-by-step explanation. A built-in process calculator lets you enter a two-digit addition or subtraction and see the answer with vertical working and stick-counting visuals — the same show-your-work approach, on demand. Designed for families: ① Apple Pencil and finger handwriting on every problem ② Auto-grading with accuracy and timing stats ③ Wrong-answer book with explanation and your draft ④ One tap generates a similar set to practice weak spots ⑤ Printable PDF worksheets — student, answer-key, and explanation versions ⑥ Bilingual: English and 简体中文, switchable at runtime ⑦ Fully offline, no ads, no accounts MathBoard is local-first: worksheets, attempts, wrong answers, and PencilKit drafts stay on the device. Nothing is uploaded. Core practice is entirely free: all problem types, number ranges, and set sizes (including comparison and two-digit) are available without paying. MathBoard Pro unlocks PDF export, full step-by-step explanations with vertical and visual models, wrong-question drills, learning reports, and batch generation — choose a Monthly or Yearly subscription, or a one-time Lifetime purchase.
