Standards
Grade and skill references come from the Common Core mathematics standards and English language arts standards. Summaries on this site are original paraphrases. Worksheets are independently generated.
Names
The 2,000 published name pages use the Social Security Administration’s national baby-name data. Names are ranked by combined birth counts across the five latest available years, 2021–2025. A name’s inclusion is a practice shortcut, not a claim about a particular child.
Word lists
Dolch pre-primer, primer and first through third grade lists and the first 100 Fry words supply familiar words for reading and spelling practice. The lists are referenced at Dolch sight words and Fry sight words. Page layout and exercises are original. Custom spelling lists come from the text you enter.
Fonts and icons
Geist, Geist Mono, Comic Neue and Playwrite US Modern are distributed under the SIL Open Font License 1.1. Full license files are included with the application. Google Fonts’ source repository supplies the fonts. Phosphor’s light icons use the MIT license. The PDF writer is FPDF 1.86, distributed with its permissive upstream license.
Original worksheet content
No third-party worksheet is copied into a download. Research references help check familiar layouts, printable margins and answer-key placement. Generated design references guided the website’s layout; they do not replace live worksheet content.
