169 free 3rd Grade trivia questions with answers — trivia quiz, new questions added Aug 2026.
67 free 3rd grade trivia questions with answers, written around what eight and nine year olds actually cover in class. There is a geography round (the seven continents, the biggest ocean, the tallest mountain, the largest US state), a space round (the eight planets, the Red Planet, the first Moon walk), animals (the fastest, the tallest, the biggest, how many legs a spider has), science (magnets, the water cycle, why plants need sunlight, where water freezes), and US history from Columbus and the Mayflower to Washington, Lincoln and Rosa Parks. The math round sticks to third grade skills: sides of a hexagon, minutes in an hour, inches in a foot, a dozen, a century, a right angle and the Roman numeral X. The reading round covers the books third graders pass around, from Charlotte's Web and Magic Tree House to Captain Underpants, Junie B. Jones and Diary of a Wimpy Kid, and a few sports and music questions round it out. Every question is multiple choice with four answers, so a child can make a smart guess, and each one comes with a short explanation that adds one extra fact. Use it as a classroom warm-up, a family quiz night or a car game. Every answer has been checked against a reference page and shows its source once you have answered.
