As part of her dissertation work, Sarah Abdo developed these activities to help students enrolled in General Chemistry to 'dust off' their math skills. (1) These "just-in-time" refreshers are aligned with chemistry content and are therefore best assigned when the content is first being covered within a course.

Copies of each refresher can be downloaded using the links below. Instructors can request answer keys by directly emailing the developer (sabdo@pdx.edu).

Each refresher has been built into Canvas, LMS import files are avaialbe via email for interested instructors.
