| seed | No | Set number from an earlier result to print exactly the same problems again, e.g. 48213. Default: a new random set. | |
| count | No | Problems per worksheet, 1 to 100. Default 20 (12 for long division). Example: 30 | |
| grade | No | School grade K to 6 that sets sensible number sizes, e.g. 2 or "3rd grade" or "K". UK "Year 3" is read as grade 2. | |
| paper | No | Paper size: letter (default) or a4. | |
| table | No | Times table or fact family to focus on: one number or a list, e.g. 7 or "6, 7, 8" or [3, 4]. For division it is the divisor. | |
| title | No | Title printed at the top, e.g. "Emma's Subtraction Practice". Default: a title from the rules. | |
| digits | No | Digits per number: 2 for 2-digit numbers, or "3x1" for 3-digit by 1-digit (multiplication and long division). Example: "2". | |
| layout | No | vertical (stacked column form, default; division uses the long-division bracket) or horizontal (on one line). | |
| within | No | Keep addition sums and subtraction starting numbers at or below this, e.g. 20 for "addition within 20". | |
| problems | No | Your own problems instead of generated ones: a list like ["12 + 7", "45 - 18", "6 x 7", "84 ÷ 4", "3/4 + 1/8", "7 + ? = 12"] or [{"a":12,"op":"+","b":7}], or pasted text with one problem per line. Up to 100. The tool computes every answer. | |
| versions | No | Number of different worksheets with the same rules (each with its own answer key), 1 to 10. Default 1. | |
| name_line | No | Print Name, Date and Score lines. Default true. | |
| operation | No | What to practise: addition, subtraction, multiplication (times tables), division, division with remainders, mixed (all four), "addition and subtraction", missing number, or fractions (adding fractions, subtracting fractions, multiplying fractions). Example: "subtraction". Default: from the grade, else addition. | |
| answer_key | No | Add answer key pages at the end of the PDF. Default true. | |
| max_number | No | Largest number to use in the problems, e.g. 12 for times tables up to 12. | |
| min_number | No | Smallest number to use in the problems (factors for multiplication, divisor and answer for division facts), e.g. 2. | |
| regrouping | No | Carrying/borrowing rule for addition, subtraction and 1-digit multiplication: none (no regrouping), required (every problem regroups) or any (default). Example: "none" | |
| denominators | No | Fractions only: like (same denominator), unlike or any. Default like up to grade 4, unlike from grade 5. | |
| allow_repeats | No | When the rules allow fewer different problems than count, repeat some to reach count. Default false (the worksheet is shortened instead). | |
| allow_negative | No | Allow subtraction answers below zero. Default false (no negative answers). | |
| missing_number | No | true for fill-in-the-blank problems like 7 + ? = 12. Default false. | |
| max_denominator | No | Fractions only: largest denominator, 2 to 20. Default 12 (8 up to grade 3). | |
