About the Colorado 1st grade reading list

This list combines books cited in Colorado Academic Standards with books from national sources that list titles for 1st grade: the Common Core State Standards (ELA), plus awards such as the Caldecott Medal, the Golden Kite Award and the Coretta Scott King Illustrator Award. ReadingList currently tracks 331 titles for 1st grade in Colorado, of which 7 carry a direct Colorado citation and 324 are grade-appropriate titles whose reading level overlaps 1st grade. Across the list, Lexile measures span 210L–740L.

1st grade sits in the K-2 grade band, where students are emerging and early readers. At this stage the emphasis is on building phonemic awareness, decoding, fluency, and a love of being read to. Assigned reading skews toward picture books, decodable texts, and short illustrated chapter books, with text complexity that, per Common Core’s Appendix A reading bands, typically falls around BR (Beginning Reader) to roughly 500L. Because readers in a single 1st grade classroom can span several hundred Lexile points, this list is best read as a starting point rather than a fixed requirement.

Colorado’s English Language Arts requirements are set by Colorado Academic Standards (cde.state.co.us). Most states pair their own standards with the Common Core text-complexity framework. The 1st grade list below blends Colorado-specific assignments with widely taught national titles. Every title links to its primary source on the book’s detail page, so you can confirm exactly where and why it is assigned.

How to use this list:match a title to your child’s most recent Lexile or guided-reading level rather than to the grade alone. Teachers building a 1st grade unit can pair a Colorado-cited core text with a grade-appropriate companion novel; parents previewing summer or supplemental reading can check each book’s content notes and challenge history before assigning it.
