Capital letters are also called uppercase letters! The word "uppercase" comes from the old days of printing when printers kept capital letters in the "upper case" (the top box) and small letters in the "lower case" (the bottom box). Uppercase letters are taller and often have different shapes than lowercase letters. For example: D is uppercase, d is lowercase; G is uppercase, g is lowercase.

The correct sentence is "The cat is sleeping." The first word "The" starts with a capital T. Every sentence you write should begin with a capital letter. This rule helps readers know where each new thought begins. Without capital letters, sentences would run together and be very hard to read. Practice: write a sentence about your day. Make sure the first word has a capital letter!

The correct sentence is "My friend and I like pizza." The word "I" is always capitalized. This is a special rule in English – no other pronoun is always capitalized. You write "you", "he", "she", "it", "we", "they" with lowercase letters, but "I" is always capital I. Remember: when you talk about yourself, use a big I, not a little i!

Emma is written correctly with a capital E! Names are special – they tell us exactly which person we are talking about. Always capitalize the first letter of someone's first name and last name. Examples: "Michael Jordan", "Taylor Swift", "Martin Luther King Jr." When you write your own name, always use a capital letter for the first letter. Your name is important – show it with a capital letter!

Monday is written correctly with a capital M! Days of the week and months are proper nouns, so they always start with a capital letter. For example: "My birthday is in June." "We have school on Friday." "December has holidays." Even when you write a date like "January 1", both words are capitalized because January is a month and 1 is a number (numbers do not need capitals).

Halloween is written correctly with a capital H! Other holidays: Christmas, Thanksgiving, Easter, New Year's Day, Valentine's Day, St. Patrick's Day, Mother's Day, Father's Day. When you write about a holiday, always use a capital letter. For example: "We eat turkey on Thanksgiving." "I love getting presents on Christmas morning."

Canada is written correctly with a capital C! All place names are proper nouns and need capital letters. For example: "I live in New York City." "We visited London, England." "The Amazon River is in South America." When you write about where you live or places you want to visit, remember to use capital letters for the names.

Mrs. Davis is written correctly with a capital M and a period! Titles like Mr., Mrs., Ms., Dr., and Prof. always start with a capital letter. They also usually have a period after them (except in some styles). When you write a letter or address someone, use their title with a capital letter. For example: "Dear Dr. Jones," or "Thank you, Mr. Smith." This shows respect for the person you are writing to.

School should NOT be capitalized in the middle of a sentence. School is a common noun – it is a general word for any school. Only proper nouns (specific names of people, places, brands, days, months, holidays) need capitals. Common nouns like dog, cat, school, park, book, and car are lowercase unless they start a sentence. Do not use capitals for every word – that is called "camel case" or "random capitalization" and it is incorrect!

The sentence has two mistakes! "my" should be "My" (capitalize the first word of the sentence), and "june" should be "June" (capitalize months). The correct sentence is "My birthday is in June." You have learned so many capitalization rules: first word of a sentence, the pronoun I, people's names, days and months, holidays, places, titles, and not capitalizing common nouns. You are becoming a writing expert. Keep practicing, and your writing will always look professional!
