This Self-Paced Significant Figures & Precision course is designed to be a short science elective to help high school students become comfortable with the rules for rounding numbers when precision and significant figures are required. Students who have been exposed to some of these rules through a science course such as chemistry or physics may find this self-paced course to be an excellent review.
