Through his research with struggling students Dr. Ted Hasselbring identified a need for a targeted math fact fluency intervention. Discouraged with drill and practice programs, Hasselbring developed the FASTT Math approach which helps students establish a lasting mental link between the facts and their answers.  
 
The FASTT Math approach has been validated over several years of research with both non-struggling and struggling students. In the study, depicted on the right, math delayed students who used the FASTT Math approach increased their fluency by more than 70%. Those students who received no intervention showed no growth.
