Capitalizing Sentences and I across the grades
Kindergarten
Two capital rules start it all: the first word of every sentence gets a capital letter, and the word I is always written as a capital. Kindergartners pick the correctly written sentence from lookalikes, training their eyes on the very first letter.
1st Grade
First graders apply both rules automatically in their own writing and catch the classic slips: a sentence that starts small, a lowercase i, or a stray capital in the middle of a sentence. Choosing the correct version from near-twins builds the editor's eye.
