AI math tutor and AI tutor for math class that names the misconception

Wrong is not a diagnosis. Students type their working on your problems, the tutor coaches with a question, and you get the specific move in the reasoning that failed.

01 The short answer

What an AI math tutor for schools has to do

An AI math tutor for a school coaches each student through the teacher's own problems without giving the answer, and reports back. Coeducate reads the typed working, asks the next question, and writes a card for the teacher naming the misconception (for example, applying a second percentage to the original price), quoting the student's own words and suggesting a five-minute reteach. Solvers that return a finished solution are a different product, and a teacher learns nothing from them.

Classroom is $89 a month for one teacher and 60 students. School covers 10 educators and 600 students for $2,088 a year, about $3.48 per student.

02 Which kind you are buying

Four kinds of AI tutor for math, and who each one serves

"AI math tutor" covers products built for very different buyers. Most of the search results are solvers aimed at students doing homework. A school buying for a class needs something else, and the honest answer is that some of these do their own job better than we would.

Kind Examples What the student gets What the teacher gets Best for
Photo solver Photomath, Mathos, MathGPT The full worked solution Nothing An adult checking their own working
General chatbot ChatGPT, Gemini An explanation, usually with the answer Nothing unless the student shares the chat Teacher planning and explanations
Practice platform with a chat helper Khanmigo in Khan Academy, Eedi Coaching inside the vendor's own questions Progress on that platform's content Schools that teach from that content library
Tutor on your own assignments Coeducate Hints and questions on the teacher's problems The named misconception, the student's words, a reteach plan Teachers and interventionists who need to know why

If your school already teaches from Khan Academy, Khanmigo is the natural pick and costs $10 per student a year on the Districts starter plan. The full comparison is on our Khanmigo alternative for schools page.

03 The problem with a cross

Twelve students, twelve different reasons

A class gets a percentage question wrong and the grade book records one fact: twelve crosses. Behind those twelve crosses are at least four different faults, and they need four different five-minute fixes, not one whole-class reteach of percentages.

Finding out which is which means reading twelve pieces of working and reconstructing what each student was thinking. It is the single most expensive thing a math teacher does, it is the first thing dropped when time runs out, and it is the thing an AI math tutor can actually take over.

  • Base confusion. Applies the second percentage to the original number.
  • Additive thinking. Assumes plus 20 and minus 20 cancel.
  • Notation slip. Reads 20% as 20 and subtracts it.
  • Arithmetic only. Method correct, one multiplication wrong.

Only the last of those needs practice. The first three need explanation, and they are invisible in a grade book.

Session evidence card, grade 6-8

Fixed example

Diagnosis

Treats percent change as additive, not multiplicative

The student assumes a 20% rise and a 20% fall cancel, because both are 20. The second percentage is taken of the new price, not the original, so the final price is $38.40.

Next tutoring move / hint only

You wrote that the 20s cancel out. Twenty percent of $40 is $8. What is twenty percent of $48, and why is that a different number?

Skill mastery read

Percent of a quantity

Secure
84%

Computed 40 + 20% = 48 correctly before the reasoning broke down.

Successive percent change

Not yet
22%

Says the 20s cancel out, applying both percentages to the same base.

Choosing the base of a percentage

Developing
41%

Subtracted 20 rather than 20% of 48, then abandoned the step.

Checking for reasonableness

Developing
55%

Noticed that is not right but reverted to the first guess.

Teacher note

Can calculate a single percentage of a quantity but applies successive percent changes to the original base, so any multi-step discount or markup problem fails.

Reteach in 5 minutes

Same percent, different base

  1. Put $40 and $48 side by side and ask for 20% of each.
  2. Have students say aloud which number each percentage is of.
  3. Repeat the shirt problem, writing the base under every step.

Produced from the student answer alone. No rubric, no score entry, no assessment window. The live demo generates the same card from any piece of work you give it.

04 Coverage

Where a math misconception usually hides

The skill vocabulary is mathematical rather than generic, which is what makes the record usable in a data meeting. A few of the fault lines the diagnosis is built to separate:

Fractions

Denominator read as a count rather than a partition. Adding denominators. Comparing by numerator size alone.

Decimals and place value

Longer decimal read as larger. Misaligned columns. Zero treated as absent rather than as a placeholder.

Ratio and proportion

Additive reasoning where multiplicative is required. Part confused with whole in a ratio.

Percent

Base confusion in successive change. Percent of a percent. Reverse percentage treated as subtraction.

Algebraic manipulation

Distribution over a bracket applied to one term only. Sign errors when moving terms. Equals treated as a result arrow.

Geometry and measure

Area and perimeter conflated. Unit conversion applied linearly to an area. Diagram read as to scale.

05 The integrity question

Math is where answer engines do the most damage

Photograph-the-question solvers were the first mass-market AI in schools and they remain the most used. They produce a complete worked solution that is indistinguishable from understanding, which is why math homework stopped being a reliable diagnostic in a lot of schools.

The default here is the opposite. In Socratic mode the next move is a question and never contains the corrected value. You can verify that yourself by flipping the toggle in the demo and reading both outputs for the same piece of work. More on the policy side in AI homework help that does not do the homework, and the questions to ask before you assign any tutor are on the AI tutoring for students page.

Running a Tier 2 pull-out group rather than a whole class? The block-by-block workflow is on the math intervention software for middle school page, and the Algebra 1 version is on the high school math intervention programs page. Already running a practice bank and wondering what a tutor adds on top? The IXL alternative comparison puts the two side by side. Working with a student who has a math learning disability? The untimed online dyscalculia intervention program page shows how the card tells a recall slip from a missing concept. Buying for your own classroom rather than an intervention block? Start with AI for math teachers.

Solver output

Final price: $38.40. Step 1: 40 x 1.2 = 48. Step 2: 48 x 0.8 = 38.40.

Correct, complete, and it tells the teacher nothing. The student copies it and the misconception survives to the exam.

Socratic output

Twenty percent of $40 is $8. What is twenty percent of $48, and why is that a different number?

The student has to do the multiplication and, more importantly, has to look at which number the percentage is of.

What the teacher gets either way

Both modes produce the same evidence card. Switching to a full worked explanation for a student who is genuinely stuck does not cost you the diagnostic record, which is why the toggle is safe to hand to a teacher rather than locked behind an administrator.

06 In the room

While the tutor coaches, you take the group that needs you

A class of 28 working on percent change splits into roughly four groups by the end of the first ten minutes. The tutor keeps coaching the students who are close. The cards tell you which six students share the base confusion, so that is the table you sit down at, with the reteach already written.

  1. 1

    Assign

    Paste or type your own problems. No content library to adopt, no rostering week.

  2. 2

    Students work

    They type their working. The tutor replies with a question, never the corrected value.

  3. 3

    Read the cards

    Each wrong answer comes back with a named misconception and the student's own words.

  4. 4

    Reteach

    Group by fault line and use the five-minute reteach on the card, today or tomorrow.

07 By grade band

Choosing an AI math tutor for middle school, high school and algebra

Best AI math tutor for middle school

Grades 6 to 8 are where fractions, ratio and percent either click or quietly break. Look for a tutor that can tell additive from multiplicative reasoning in a student's own sentence, because that one distinction explains most wrong answers in these years. The Tier 2 version of this workflow is on the math intervention software for middle school page.

Best AI math tutor for high school

In high school the visible error is usually in algebra, but the cause is often a prerequisite from grade 7: a sign rule, distribution over one term, or the equals sign read as "the answer is". A useful tutor names that prerequisite instead of logging "cannot solve equations". See the high school math intervention programs page.

AI math tutor for algebra

Algebra 1 double blocks and support periods need dated evidence more than they need more practice items. Each session here writes a per-skill record by student, so the on-track conversation in spring starts from what each student actually wrote, not from a single benchmark score.

08 Price

What an AI math tutor costs per student

School AI tutors are mostly quoted. Ours is published, so the per-student number is simple arithmetic. Khanmigo's Districts starter price is shown for comparison, re-read on Khan Academy's site in October 2026.

Plan Covers Per year Per student
Coeducate Classroom 1 teacher, 60 students $528 $8.80
Coeducate School 10 educators, 600 students $2,088 $3.48
Khanmigo Districts Enterprise Starter Up to 1,000 student licenses $10 per license $10.00

Monthly billing is also available: $89 a month for Classroom and $349 a month for School. Pricing detail for the other math programs schools usually compare, such as i-Ready cost per student and Zearn cost per school, is in our pricing articles.

09 Questions

AI math tutor questions schools ask

What is the best AI math tutor?

The best AI math tutor depends on who is buying. For a student who wants a worked answer tonight, photo solvers are fastest. For a school, the best AI math tutor coaches with questions instead of answers and tells the teacher what went wrong. Khanmigo does the coaching inside Khan Academy content. Coeducate does it on your own assignments and writes a per-skill record naming each misconception.

Is there an AI math tutor?

Yes. There are three kinds. Solvers photograph a problem and return the full solution. Practice platforms add a chat helper to their own question bank. Tutors for schools, like Coeducate, coach a student through your problems with hints, never the corrected value, and send the teacher a card with the misconception, the student's own words and a five-minute reteach.

Can ChatGPT tutor math?

ChatGPT can explain math well, but out of the box it gives answers, makes occasional arithmetic errors and keeps no record a teacher can use. A student who asks for help usually gets the finished solution. A school tutor is built the other way round: it withholds the answer, checks the student's working step by step and reports each student's fault line to the teacher.

Is there a free AI math tutor?

Yes for individual students: several solvers and chat tools have free tiers, and Khanmigo costs learners $4 a month. What is rarely free is a tutor a school can run for a whole class, because every student session costs money and the teacher reporting has to work. Coeducate is paid, from $89 a month, and the demo on this page runs without an account.

How much does an AI math tutor cost?

For a school, from about $3 to $15 per student per year. Khanmigo Districts Enterprise Starter is $10 per student a year for up to 1,000 licenses. Coeducate publishes its prices: Classroom is $528 a year for one teacher and 60 students, about $8.80 per student, and School is $2,088 a year for 600 students, about $3.48 per student.

Can AI replace a math tutor?

Not a good human tutor working one to one, and a school should not buy it on that promise. What AI does well is the part a teacher cannot scale: sitting with every student during practice, asking the next question and writing down exactly where the reasoning broke. The teacher then spends small-group time on the students and misconceptions the record points to.

What is the best AI math tutor for middle school?

For grades 6 to 8, pick a tutor that separates the misconceptions that dominate those years: fractions, ratio and proportion, percent change, negative numbers and early equations. It should coach without giving answers and group the class by fault line. Coeducate is built around that middle school skill vocabulary and is the core of our math intervention software for middle school.

Is using an AI math tutor cheating?

It is cheating when the tool does the work, which is what photo solvers do. A tutor that only asks questions and never shows the corrected value cannot hand a student a finished answer to copy. In Coeducate the default Socratic mode never contains the answer, and the teacher sees every exchange, so the practice stays the student's own work.
