Average Atomic Mass Practice
This 2-page practice set guides 10th graders through calculating average atomic mass, with fill-in-the-blank scaffolding for each step. It focuses on using decimal abundances directly in the calculation.
“make an average atomic mass practice with step by step fill in scaffolding without converting abundance to percent just dividing by 100 as part of the calculation”
Teacher Guide & Tips
- Use this practice set as a 30-minute independent work activity or homework assignment.
- Discussion question: Why is it important to use the decimal form of abundance (not the percentage) when calculating average atomic mass?
- For struggling learners, model the first problem together as a class, emphasizing where each number in the formula comes from.
- Advanced learners can be challenged to create their own average atomic mass problem, including identifying the elements and their isotopic abundances.
