MathBoard is an iPhone and iPad mental-arithmetic worksheet and handwriting whiteboard app for families with young children — generate a worksheet in one tap, let your child solve it by hand, then auto-grade and review wrong answers. Core practice is entirely free; MathBoard Pro adds vertical step-by-step explanations, learning reports, and PDF export.
What it does
Pick a problem type and range, and MathBoard generates a fresh worksheet of mental-arithmetic problems. Each problem comes with its own whiteboard draft area that supports Apple Pencil and finger writing, so children can lay out vertical sums, work the steps, and show their thinking. When practice is done, MathBoard grades it automatically and shows accuracy, correct and wrong counts, and time spent.
Problem types
- Addition within 10 / Subtraction within 10 — first counting and combining.
- Mixed add & subtract within 20 / 50 / 100 — everyday mental-arithmetic fluency.
- Multiplication tables / Division tables / Mixed × ÷ — times-tables fluency.
- Two-digit add & subtract — with and without carrying and borrowing.
- Compare sizes — greater-than / less-than practice.
- Four operations mixed — add, subtract, multiply, and divide together.
Process calculator
MathBoard also includes a keypad-style process calculator. A child enters a two-digit addition or subtraction and sees the answer with vertical (column) working and stick-counting visuals — the same show-your-work approach, on demand. From any worked result, one tap generates a similar worksheet to keep practicing.
Practice loop
- Generate a worksheet with custom count, number range, operations, carry/borrow, negatives, and comparison.
- Practice on the whiteboard with a PencilKit draft for each problem — write with Apple Pencil (on iPad) or your finger.
- Auto-grade and review accuracy, correct/wrong counts, and time.
- Wrong-answer review with the child's answer, the correct answer, and the draft.
- Re-practice similar problems generated from each mistake.
- Export PDF (Pro) — student practice version, teacher answer version, or wrong-answer explanation version.
Built for families
MathBoard is local-first: no account, no ads, no analytics or tracking SDKs, and no collection of children's personal information. Worksheets, attempts, wrong answers, settings, and whiteboard drafts stay on the device. It is bilingual (English and 简体中文) and works in light and dark appearance. Suitable for pre-school transition and grades one and two.
