Increasingly individuals with Intellectual Disability (ID) are showing the capability of learning abstract mathematical skills like algebra. The purpose of the study was to show a method for teaching high school-aged individuals with ID the algebra skill of creating an equation from a line using a time-delay strategy and equation template. We employed a non-concurrent multiple probe across participants design with four participants who showed an increase in performance after the intervention. All participants showed improvements with a percentage of a nonoverlapping data effect size of 86.84%. The study supplied more evidence that the use of time delay approaches can …
