What Is Flipped Math and How Does a Flipped Math Classroom Work?
Updated
Flipped math is an instructional model in which students learn new concepts at home through short videos and then use class time for practice, questions, and mastery checks. It works best when students can reliably watch videos outside class and when the teacher is ready to run a classroom organized around individual progress rather than whole-group lectures. The version described on flippedmath.com goes one step further: it is flipped-mastery, meaning students must demonstrate mastery of each concept before moving on, and they progress at their own pace.
The core idea: video first, practice in class
In a traditional math class, the teacher explains a new method during class and students practice afterward at home. Flipped math reverses that order:
- Before class: Students watch a short instructional video on the next concept and take notes.
- During class: Students work problems, ask the teacher and classmates for help, and complete checks that show whether they have mastered the concept.
- After mastery: The student moves to the next concept or unit.
The point is to move the teacher's direct explanation to a format students can pause, rewind, and rewatch, and to move the harder work — actually doing math with support nearby — into the classroom.
What makes it flipped-mastery
Flipped-mastery adds a pacing rule to the flipped model. According to flippedmath.com, the approach "allows students to demonstrate mastery of all concepts and progress at their individual pace," and students are expected to "master all standards in Algebra, Geometry, Algebra 2, Pre-Calc, and Calculus."
In practice this means:
- A student does not advance to the next unit just because the class calendar says so.
- A student advances when they can show they have mastered the current standard.
- Different students in the same room may be working on different topics at the same time.
This is the key difference from a standard flipped classroom, where the whole class still tends to move through the same material on the same schedule.
How a flipped-mastery classroom typically runs
The exact routine varies by teacher, but the structure implied by the flippedmath.com model looks like this:
- Watch and take notes. The student views the assigned video for a concept and records the method and examples.
- Practice. The student works through problems on that concept, in class, where help is available.
- Check for mastery. The student completes a mastery check — a short assessment of that specific concept.
- Pass or revisit. If the student demonstrates mastery, they move on. If not, they review the video and practice more, then retry.
- Repeat. The cycle continues concept by concept, with the teacher tracking where each student is.
The teacher's role shifts from lecturing to the whole group to circulating, diagnosing individual misunderstandings, and managing many students at different points in the curriculum.
How it differs from a traditional math class
| Dimension | Traditional math class | Flipped-mastery math class |
|---|---|---|
| First exposure to a concept | Teacher explains in class | Student watches a video before class |
| Class time use | Lecture, then some practice | Practice, questions, and mastery checks |
| Homework | Practice problems | Watching videos and taking notes |
| Pacing | Whole class moves together | Each student moves on after mastering |
| Teacher role | Primary explainer to the group | Guide and diagnostician for individuals |
| Retakes | Often limited | Built into the mastery cycle |
What students need to succeed
Flipped-mastery puts more responsibility on the student than a lecture-based class does. Students who do well typically:
- Watch the videos on schedule. Skipping the video means arriving at class without the concept, which stalls the whole cycle.
- Take usable notes. Notes should capture the method and worked examples so they can be referenced during practice.
- Self-check honestly. Students need to recognize when they do not actually understand a concept rather than pushing forward.
- Ask for help in class. Since class time is the main opportunity for support, using it matters.
- Manage their own pace. Self-pacing is an advantage only if the student keeps moving.
Common misunderstandings and limits
"Flipped means the teacher doesn't teach." Not accurate. The teacher still teaches — through the videos they create or select, and heavily through one-on-one and small-group instruction during class. What changes is when and how direct explanation happens.
"It's the same as any flipped classroom." Flipped-mastery is a specific variant. A flipped classroom can still keep the whole class on one schedule; flipped-mastery does not.
"It suits every student equally." Self-pacing rewards students who are organized and self-directed, and it can be difficult for students who struggle to work independently or who need external deadlines. The model also assumes students can access videos outside class, which depends on device and internet availability.
"Mastery means one attempt." In a mastery model, the expectation is that students keep working until they demonstrate mastery, which usually means retakes and revision rather than a single high-stakes test.
Where to see the model in detail
flippedmath.com hosts courses across Algebra 1 (Common Core and Traditional), Algebra 2, Geometry, Pre-Calculus, Math 7, AP Calculus, and AP Statistics, along with student resources such as Desmos and a TI-84 emulator, quick-review topics, and teacher materials including pacing guides and an explanation of how flipped-mastery works. The site also notes that the courses are taught by four teachers with over 70 combined years of high school math instruction experience, and it credits Aaron Sams with originating the idea in December 2010. If you want to understand the model before adopting it, the site's "How Flipped-Mastery works" section and its student, parent, and teacher FAQ pages are the most direct starting points.
