免費 · App 內購買 · 專為 iPad 設計。尚未針對 macOS 驗證。
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.
