Use commas to separate items in a list of three or more things. For example: 'I like apples, oranges, and bananas.' Notice the comma before 'and' (called the serial comma)—many Grade 4 teachers require this. Use commas when listing, not when describing single items.
Ask yourself: 'Does something belong to someone?' If yes, you need an apostrophe. For one owner: add 's (the boy's book). For multiple owners, the apostrophe goes after the s (the boys' books). If the plural doesn't end in 's,' add 's (the children's toys). If you're just making a word plural without showing ownership, no apostrophe is needed.
The period or question mark goes inside the quotation marks, right after the last word the person spoke. For example: She said, 'What time is it?' or He answered, 'It's three o'clock.' The punctuation mark that ends the dialogue goes inside the marks, not outside.
Each punctuation mark has a different job. Commas help readers pause and understand lists or separate ideas. Apostrophes show that something belongs to someone or that two words are joined together. Quotation marks show the exact words someone said. Using the right mark helps readers understand your writing clearly, just like using the right tool makes a job easier.

A contraction combines two words into one shorter word, like 'do not' becomes 'don't' or 'cannot' becomes 'can't.' A possessive shows that someone owns something, like 'the cat's toy.' To tell them apart, try replacing the apostrophe: if you can separate it into two words (don't → do not), it's a contraction. If you can't (cat's doesn't equal 'cat s'), it's a possessive showing ownership.
