Decimals and Place Value Games for Grades 1‑8
Place value is the idea that a digit means something different depending on where it sits, and decimals simply extend that idea to the right of the point. The games here practise reading and building numbers, rounding, comparing decimals, adding them, and estimating an answer before calculating. Students who understand place value rarely mix up 0.5 and 0.05. Rounds are quick and every wrong answer reveals the right one, so players learn the pattern rather than guessing.
