Multiplication Worksheet Generator
Create randomized integer multiplication practice with unique-answer missing factors, measured multipage PDFs and matching answer keys.
Your inputs stay in your browser.Integer factors 0-20, 1-100 questions and 2-4 columns. A stored set powers puzzle/key/combined PDFs; alternate exports do not redraw random facts. Missing factors require a nonzero visible factor. Drafts stay in tab memory only; refresh clears them. Fonts are bundled locally; unsupported glyphs and unreadable text block export instead of disappearing.

How to use Multiplication Worksheet Generator
Set inclusive factor ranges, question count, columns and product/factor-missing style. Repeats are allowed by default; turn them off for ordered fact uniqueness, optionally collapsing mirrored facts. Generate once, then choose worksheet/key/combined downloads. Preview page counts before printing; text and JSON retain original question IDs.
Worked example
A 2-3 and B 4-5 gives four ordered facts without repeats; five questions must be rejected. For missing factors, blank × 5 = 0 uniquely answers zero; 0 × blank = 0 is not eligible because it has no unique answer.
Rules and limits
Factors 0-20 with minimum no greater than maximum; 1-100 questions; 2-4 columns; A4/Letter portrait; title 80 code points. Mirrored collapse only combines pairs that both exist within the designated ranges. Crypto rejection sampling selects facts and eligible hidden sides uniformly. Questions stay at least 12 pt and paginate with writing space; key pages follow puzzle pages. Alternate exports never rerandomize. Configurable practice, not certified teaching or assessment.
