Alternative Base Systems Worksheets

Name: Alternative Base Systems for Cross-Curricular Fun and Engineering Applications
Type: Educational
Summary: Worksheets and instructional sheets for teaching a variety of non-decimal bases and a few of their uses.
Author: Jen Seron and Dan Simon
Nature: Download
A total of 22 (two dozen and two) worksheets and instructional sheets for teaching non-decimal bases and their applications, specifically designed around an engineering context. First used at the American Society for Engineering Education conference in Atlanta in 11E9 (2013.), these sheets were designed by DSA secretary Jen Seron, a professional educator, and will be a boon to those trying to open the concept of non-decimal bases for younger students.
