Free Decimals Practice for Grade 4

Fourth grade is when decimals show up for real, and the single biggest mistake students make is forgetting to line up the decimal points. These add-and-subtract problems use tenths so the calculations stay manageable while your child builds the habit of writing problems vertically and aligning the decimal first. If they're getting wrong answers, look at their scratch work — nine times out of ten, it's a misalignment, not a math error. Once that habit is solid, decimal arithmetic follows the same rules as whole numbers.
