Three rules that fix most capitals
Early capitalization comes down to three rules: capitalize the first word of a sentence, the names of people, and the word I every single time. Master these and most sentences look right.
How to use it
For each sentence, ask “Which letters should be big?” — the first word, any name, and the word I. Have your child underline what they changed. Pairs with end punctuation.
