1st Grade Capitalization Worksheets

First graders should know and consistently apply several capitalization rules per CCSS L.1.2a: capitalize the first word in a sentence, capitalize the pronoun I, capitalize proper nouns including people's names, days of the week, and months of the year, and capitalize the names of specific places (cities, states, school names). This builds on kindergarten's three-rule foundation by adding days, months, and place names. Students should also capitalize titles in names (Dr. Smith, Mr. Jones). Worksheets that present sentences with missing capitals and ask students to rewrite them correctly build practical editing skills. Calendar-based activities where students practice writing days and months with capital letters connect capitalization to daily routines. Dictation exercises, where the teacher reads a sentence and students write it with correct capitalization, assess whether students can apply rules independently. First graders should also begin proofreading their own writing for capitalization errors, developing the self-editing habit that is essential for writing development in second grade and beyond.
