Tools (8)

build_name_tracing_worksheet_configread-onlyConfigure custom student name tracing repetition rows, progressive fade-out scaffolding (solid guide -> dashed trace -> independent baseline), and paper orientation.
calculate_us_letter_vs_a4_printable_marginsread-onlyCalculate 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.
explain_order_of_operations_step_treeread-onlyBreak down multi-step arithmetic expressions with parentheses, exponents, multiplication/division, and addition/subtraction for Grade 5-6 worksheet answer keys.
generate_fraction_number_line_coordinatesread-onlyCompute 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.
generate_seeded_math_drill_setread-onlyGenerate a reproducible set of K-12 arithmetic, fraction, or order-of-operations practice problems with exact answer keys using deterministic mulberry32 PRNG.
list_paperlesson_printable_generatorsread-onlyList all free true-vector PDF worksheet generators on PaperLesson with direct pre-configured landing URLs.
lookup_cursive_stroke_group_progressionread-onlyRetrieve the optimal stroke-family teaching order for cursive lowercase and uppercase letters (undercurve, downcurve, overcurve, slant connectors) rather than alphabetical order.
lookup_handwriting_ruling_specsread-onlyLook 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.
