Product Description

Understanding and calculating using significant figures (or significant digits) is one of the fundamental skills of Chemistry and Physics. The concepts of accuracy, precision, uncertainty, and error in measurements and calculations can be challenging for students, especially when encountering them for the first time. These are the kind of skills that need to be actively practiced, and not just passively studied from a distance. When students have the opportunity to use their new skills repeatedly, along with teacher feedback, they are more likely to internalize their understanding of the rules and process.

This one-sided worksheet includes both practice identifying the amount of significant figures in a given number and practice rounding number to a specific amount of significant figures. The values given for identifying significant figures include examples of all of the significant figure rules, including items that are common sources of confusion for students. The same set of six numbers is used for each level of rounding practice, to help them see the connections between the rounding rules and specific numbers.

In my classes I use this worksheet as a review of significant figures before moving onto Mole Calculations and Stoichiometry. It would also be great as part of lesson introducing significant digits or as an assessment after other independent practice.

I also have a worksheet on rounding answers correctly using significant figures, using both the addition/subtraction rules and multiplication/division rules. Check it out by clicking the link below:
