Significant Figures Practice Worksheet
Give students focused practice mastering significant figures (sig figs) with this ready-to-use worksheet! This resource is perfect for reinforcing one of the most important measurement skills students will use throughout Physics, Chemistry, AP Physics, and introductory college science courses. NGSS aligned, supporting skills & practices.
Students practice identifying and applying significant figures so they can report measurements and calculated values with an appropriate level of precision.
Skills Practiced
This worksheet provides practice with:
Identifying the number of significant figures in a value
Recognizing which zeros are significant
Working with decimal values and trailing zeros
Applying significant figure rules
Rounding answers to the correct number of significant figures
Connecting significant figures to measurement precision
Building accuracy and confidence with scientific calculations
Why Significant Figures Matter
In experimental science, measurements are never infinitely precise. Significant figures communicate the precision and reliability of measured quantities, making them an essential skill for laboratory work, calculations, data analysis, and scientific communication.
This worksheet helps students move beyond simply memorizing sig-fig rules and become more comfortable applying them to the types of numerical values they will encounter throughout a physics or chemistry course.
