## Tools Provided (8 Read-Only Tools)

| Tool Name | Summary |
| :--- | :--- |
| `generate_seeded_math_drill_set` | Generate a reproducible set of K-12 arithmetic, fraction, or order-of-operations practice problems with exact answer keys using deterministic mulberry32 PRNG. |
| `lookup_handwriting_ruling_specs` | Look up exact physical millimeter and PostScript point (72 pt/inch) baseline, midline (x-height), and descender spacing for Pre-K through Grade 5 handwriting paper. |
| `build_name_tracing_worksheet_config` | Configure custom student name tracing repetition rows, progressive fade-out scaffolding (solid guide -> dashed trace -> independent baseline), and paper orientation. |
| `lookup_cursive_stroke_group_progression` | Retrieve the optimal stroke-family teaching order for cursive lowercase and uppercase letters (undercurve, downcurve, overcurve, slant connectors) rather than alphabetical order. |
| `generate_fraction_number_line_coordinates` | Compute exact vector tick coordinates and benchmark labels for teaching proper fractions, improper fractions, and equivalent fractions on a 0-to-1 or 0-to-2 number line. |
| `explain_order_of_operations_step_tree` | Break down multi-step arithmetic expressions with parentheses, exponents, multiplication/division, and addition/subtraction for Grade 5-6 worksheet answer keys. |
| `calculate_us_letter_vs_a4_printable_margins` | Calculate exact PostScript vector coordinates (pt) and safe classroom printer margins (0.5 in / 12.7 mm) to prevent edge clipping across US Letter and ISO A4. |
| `list_paperlesson_printable_generators` | List all free true-vector PDF worksheet generators on PaperLesson with direct pre-configured landing URLs. |
