About Gap Math

Gap Math is educational practice software for math classes in grades 6 to 12. Students get short, timed practice on the fluency skills that algebra depends on: adding and subtracting negative numbers, perfect squares and square roots. It was built by a high school math teacher for classroom warm-ups and short homework practice.

Privacy. Gap Math has no logins, no ads, no chat and no links to other sites. It collects no student data. Nothing a student types leaves the device; a personal best score is stored only in that browser.
