Our Rounding to the Nearest 10 worksheet provides essential practice for 2nd and 3rd graders learning to estimate and approximate numbers, a foundational skill used throughout everyday math and problem solving.

How to Solve Rounding

Look at the ones digit of each number to decide whether to round up or down. If the ones digit is 0, 1, 2, 3, or 4, round down to the nearest ten. If the ones digit is 5, 6, 7, 8, or 9, round up to the next ten. For example, 34 rounds down to 30, while 37 rounds up to 40.
