Sophia: Adding and Subtracting Using Significant Figures: Lesson 1

In this significant figures instructional activity, students solve nine problems. They indicate significant figures in given numbers, they perform calculations and express their answers with the proper number of significant figures and...

In this significant figures worksheet, students indicate the number of significant figures in given measurements. They also perform calculations of multiplication, division, addition and subtraction and identify the number of significant...

Selecting the proper measurement requires thought; for example, an odometer shouldn't be used to measure millimeters due to a lack of preciseness. An informative video from a Socratica playlist explains the importance of significant...

Are your lab results both accurate and precise? An interesting video lesson explains the difference between the two descriptions. Using error and percent error measurements, these descriptions become concrete and in turn leads to a...
