Getting a kid through middle school math using only Khan Academy is possible but it requires a setup that most people overlook until their kid hits a wall around unit fractions or linear equations.
Khan Academy isn't a curriculum in the traditional sense. It's a skill-tree generator that auto-generates practice problems, tracks mastery, and assigns exercises based on performance. You still need to be the one deciding what gets covered, when it gets covered, and what happens when your kid gets stuck and the AI tutor loop just asks the same question in slightly different words for the fourth time. Start by creating accounts for each kid and then immediately go into the dashboard to adjust the goals. By default Khan Academy tries to fill a full grade level per year. That is fine for some kids. It is rough for kids who need more time on foundations or who are jumping ahead in certain areas. Go to Settings > Course Goals and set them to something like "two units per week" instead of the default pace, which tends to push completion in about eight to ten weeks per grade level. Before you do anything else, install the desktop browser extension or use a tablet. The mobile app is functional but the UI compresses things enough that navigating the parent dashboard on a phone is a headache. The desktop version loads the progress charts and assignment tools without the extra taps.
Here is the part nobody tells you: Khan Academy does not provide teacher explanations. The videos are there, they are competent, but they are one-size-fits-all. If your kid learns best from a different pacing or a different way of explaining something, you are going to need a second source. I keep a pdf copy of the relevant module from the Common Core State Standards aligned curriculum, usually from Illustrative Mathematics or Openup Resources, and pull it up when the Khan video just does not land. That takes about two minutes to set up per topic and saves an hour of frustration. The assignment feature is where Khan Academy actually becomes usable as a homeschooling tool. Instead of letting your kid drift through units at their own pace without structure, you can assign specific exercises for a given day. Go to Assignments > Create Assignment and select the exact skills you want covered. Set a due date. Your kid completes the work and you see a report the next day showing time spent, accuracy, and which problems triggered hint loops. This replaces whatever grading system you were using before and cuts your daily check-in from maybe thirty minutes down to about five. One specific edge case I ran into: my kid hit the geometry unit and Khan Academy assumed knowledge of coordinate plane skills that weren't formally tagged as prerequisites. The system kept assigning coordinate geometry problems without any review unit. The kid was stuck on a feedback loop for about three weeks because the platform did not offer a standalone coordinate plane refresher. I worked around it by pulling the relevant skill sheets from the Illustrative Mathematics curriculum, doing a two-session review, and then feeding those specific problem types back into Khan by assigning the individual skills directly rather than letting the adaptive algorithm choose them. After that the geometry track ran smoothly. The fix took roughly forty-five minutes total.
The progress reports are the other reason people commit to this. The mastery chart shows exactly which skills are at each level: foundational, developing, mastery, or above mastery. It is actually useful for tracking gaps that standardized tests might miss. If your kid is scoring well on general math quizzes but the chart shows "proportional reasoning" sitting at the foundational level for six weeks, that is a signal to pause the current unit and drill that skill before moving forward. There is a free trial for Khan Academy's premium features but honestly the free version covers the core needs. Khanmigo, the AI tutoring assistant, is available on the paid tier and it is passable for basic guidance but not reliable for higher-level math or for kids who need Socratic questioning rather than direct answers. I found it helpful for middle school science and history explainers but would not rely on it for algebra proofs or calculus derivatives. The biggest limitation is that Khan Academy does not assess written work or open-ended responses in math. If your homeschooling plan includes proof writing, short answer explanations, or word problem breakdowns, you are going to need a separate system for that. I use a simple Google Doc for each unit where the kid writes out their reasoning on three selected problems per week. You grade those yourself or cross-check them with answer keys from the curriculum you are supplementing with. This adds maybe fifteen minutes per session but closes the gap that Khan's purely multiple-choice and fill-in-the-blank format leaves wide open.

Another thing people miss: the mastery system is not the same as retention. A kid can reach mastery on long division in a week and then forget the procedure entirely by the time they hit multi-digit multiplication six weeks later. I recommend scheduling a monthly review session where you assign the previous unit's skills back into the practice pool. Khan Academy does not auto-schedule reviews but the platform lets you reassign old skills, so you just copy the skill IDs from the progress dashboard and create a quick assignment called "Monthly Review." This takes about five minutes and prevents the kind of skill erosion that shows up when you take a placement test six months into a program. For subjects other than math and science, Khan Academy is less comprehensive. History and reading comprehension have content but it is not as extensive and the adaptive tracking is not as tight. If you are primarily using Khan Academy for math and want another source for humanities, the usual go-to for that is either Odyssey Literary Perspective for reading analysis or a simple unit study approach where you pair a textbook with primary source documents. Khan works well as a math backbone and a supplementary resource elsewhere, not as a full curriculum replacement for everything. To get started, go to khanacademy.org and create a free account. Select "I am a student" for the kid's profile and "I am a parent/teacher" for the guardian side so you get access to the dashboard. Once you are in, set the course goal, create your first assignment, and check the progress report after three days to see how the adaptive system is placing your kid. If the placement seems off, you can retake the unit placement quiz from the course homepage and reset the starting point.
The whole process from zero to first completed assignment typically takes about twenty to thirty minutes. After that you are managing a weekly rhythm of assignments, checking reports, and pulling in a second source when the Khan videos fall flat for a particular topic. That is the actual workflow. There is no secret hack beyond being willing to supplement the gaps where the platform is thin.
