  • 1Match capital and lowercase letter pairs (A↔a, B↔b, …)
  • 2Explain when to use a capital letter: start of a sentence, names, and the word I
📘

Mini Lesson

Every letter in the alphabet has two forms — a capital (big) form and a lowercase (small) form. They look different, but they stand for the exact same sound!

Use a capital to start a sentence

  • The first word of every sentence begins with a capital letter.
  • Example: My cat is fluffy.
  • After a period, the next sentence starts with a capital again.

Use a capital for names

  • People's names always start with a capital letter.
  • Example: Sam, Maria, Ben.
  • Pet names and place names get capitals too.

The word I is always a capital

  • When the word I stands alone, it is always written as a capital.
  • Example: I like apples.
  • This is true even in the middle of a sentence.

Use lowercase everywhere else

  • All other words in a sentence use lowercase letters.
  • Example: The dog ran fast.
  • Using ALL CAPITALS for normal words is incorrect.

Ask yourself: "Does this word start a sentence, is it a name, or is it the word I? If yes — use a capital!"

Guided Practice

Trace each capital and lowercase letter pair. Say the letter name aloud as you write the big form and then the small form.
