# Rounding to Significant Figures Worksheets

Rounding to significant figures worksheet pdfs are a surefire hit with high school students and help comprehend the degree of accuracy and precision in any measurement. Begin by looking for a decimal point, and then apply the Atlantic-Pacific Rule. To round off to "so many" significant digits, count digits from the Pacific side (left to right), starting with the first non-zero digit for decimals, and then round off from there. As for whole numbers, it is from the Atlantic side (right to left). Rounding helps you decide on which numbers to drop, and the last number indicates if it has to be rounded up or rounded down.
