Online math intervention programs and online math remediation that report why each student missed
Most online intervention minutes happen with no math teacher watching: on a device cart, after school, in summer, at home. Coeducate tutors each student with questions and sends the teacher the idea that broke. Paste a student answer into the panel to see it.
Grades 3 to 12, in the browser on Chromebooks. From $5.80 per student a year on the School plan.

The short answer
What an online math intervention program has to send back
An online math intervention program gives students who fell below benchmark extra, targeted math work on a device, and it only helps if someone acts on what happens there. The useful ones send the teacher more than minutes and a percent. Coeducate is an AI tutor that questions each student on an item from their gap, never hands over the answer, and writes a dated card naming the misconception in the student's own words.
It is not a curriculum, not a screener and not a probe. Schools keep their program and their progress monitoring. The tutor covers the online minutes that today produce practice but no diagnosis.

01 Where it runs
Four places online math remediation happens without a math teacher in the chair
Districts buy online programs because there are more struggling students than adult minutes. That is the right reason. The catch is that the online minutes land exactly where no one is listening to how a student thinks, so the program has to do the listening and write it down.
01
Intervention block on a device cart
One adult, a table group and the rest of the class on Chromebooks.
What goes wrong
The students on devices are the ones nobody hears. Their wrong answers turn into a percent on a dashboard.
Each student on a device works an item with the tutor, and the adult reads the reason before the next rotation.
02
After-school program
A paraprofessional or a tutor from an outside provider, often not a math teacher.
What goes wrong
Staff can supervise but cannot always diagnose. The day teacher never sees what happened at 4 pm.
The card from the 4 pm session lands in the day teacher's report the next morning.
03
Summer bridge
Three to five weeks, new staff, mixed grades and no relationship with the students yet.
What goes wrong
There is no time to learn each student, so everyone gets the same review packet.
The first two sessions sort the summer group by misconception, not by last spring's score.
04
Virtual school or home
A student alone at a laptop, with a teacher who sees a log afterward.
What goes wrong
Answer engines are one tab away and do the item for them. Minutes go up while learning does not.
Hints and questions, not answers, and a record of the student's own explanation.
02 What schools buy
Online math intervention software compared by what the teacher gets back
Four kinds of product sell under "online math intervention". They are not substitutes for each other, and the right column is the one most demos skip.
| Kind | Examples | What the student does | Live adult needed | Typical price | What the teacher gets back |
|---|---|---|---|---|---|
| Adaptive practice software | IXL, i-Ready, Zearn, DreamBox | Practice items at their level, with hints or short videos | No | $8 to $30 per student a year, by quote | Minutes, skills passed and missed |
| Video lesson program | Ascend Math, Khan Academy | Watches a lesson, then practices the skill | No | Free to per-student licenses | Lessons watched, quiz scores |
| Live online tutoring | Tutoring vendors and district tutor corps | Works with a human tutor over video | Yes, the tutor | About $1,200 to $2,500 per student a year | Tutor session notes, quality varies by tutor |
| AI tutor with teacher reports | Coeducate | Explains their step to a tutor that asks questions, not answers | No | $5.80 per student a year at 600 students | The named misconception, the student's words, a reteach plan |
Software prices come from the district quotes we compiled for IXL cost per student and Zearn pricing for schools. The tutoring range is the National Student Support Accelerator figure explained on the high dosage tutoring programs page. Most districts end up with practice software plus one of the last two rows, because practice alone tells you what was missed and not why.
03 Example output
What the teacher reads the morning after a home session
The item and what the student wrote
Order from least to greatest: 0.4, 0.35, 0.402. "0.4, 0.35, 0.402, because 4 is the smallest number and 402 is the biggest."
The practice platform marked this "comparing decimals, 3 of 10" and served ten more decimal items, which the student guessed through. The card says the student reads digits after the point as a whole number, which is a place value gap and needs a different reteach than more ordering practice.
Session evidence card, grade 6, comparing decimals, home session
Fixed exampleDiagnosis
Reads the digits after the decimal point as a whole number
The student ranks 0.35 above 0.4 because 35 is more than 4, and 0.402 above both because 402 is the largest. Asked how many tenths are in 0.4, the student said four, then said 0.35 has thirty-five tenths. Tenths and hundredths are being read as one undivided number, so the ordering rule is not the problem.
Next tutoring move / hint only
You said 0.4 has four tenths. How many tenths does 0.35 have before we look at the 5?

04 Before you sign
Nine questions to ask any online math intervention vendor, with our answers
Ask every vendor on your shortlist the same questions. Where our answer is no, it says no.
Yes
Does it run on our Chromebooks with nothing to install?
Yes. It runs in the browser on phones, tablets and Chromebooks.
Yes
How do students sign in?
Google Workspace for Education on the School plan. Clever, ClassLink and SAML on District.
Yes
Will it give students the answer if they ask?
No. Hints and questions are the default, and the student explains each step.
Yes
What does the teacher see after each session?
A dated card with the misconception, the student's words and a reteach, plus a CSV export.
Yes
Is student work used to train a model?
No. Model inference runs under terms that exclude training use.
Yes
Which grades does it cover?
Grades 3 to 12. It reads written reasoning, so it is not built for K to 2.
Not yet
Does it carry an ESSA evidence tier?
No. There is no efficacy study yet. Pair it with a rated program if the funds require one.
Not yet
Has an outside auditor reviewed security?
No SOC 2 report and no external penetration test report today.
Not yet
Which languages does it support?
English only today.
The full privacy posture, including FERPA school-official terms and COPPA school consent, is on the student data and COPPA page. If the purchase has to cite an evidence tier, start from the research based math intervention programs list and add the tutor beside a rated program.
05 How it runs
Rolling out an online math intervention program in one grading period
Week 1
Pick the online minutes
List where students already work on devices without a math teacher: the rotation, the after-school room, summer, home.
Weeks 1 to 2
First two sessions
Each student works two or three items from their screener gap with the tutor. The cards sort the group by reason.
Weeks 3 to 8
Reteach by reason
Adults teach small groups from the cards. Students keep two short tutor sessions a week alongside the practice software.
Week 8
Team review
Probe trend plus dated cards. The team sees who moved and, for the rest, which idea keeps breaking.
Inside the school day the same tutor sits as one station of a small group block, as shown on the Tier 2 math intervention programs page. For grades 6 to 8 the math intervention software page covers the middle school version, and the high school math intervention programs page covers Algebra 1.
06 Being straight about it
When this is the wrong online math intervention program to buy
- You want students to log practice minutes. Adaptive practice software does that better and has a far bigger item bank. Buy it, and add the tutor only if you also need to know why students miss.
- Nobody will read the reports. The cards are only worth something if an adult acts on them within a week. Without that, a cheaper practice tool gives the same result.
- The students are in kindergarten to grade 2. Early math is counting and quantity with objects, and the tutor reads written reasoning. It starts at grade 3.
- The grant requires an ESSA tier on this line item. Fund a rated program with the restricted money and place the tutor on a general line.
07 Who uses it
Built for the people who own the online minutes
District math coordinator
Already pays for practice software and wants to know why the usage reports do not move the screener.
After-school or summer director
Staffs rooms with paraprofessionals and tutors who are not math specialists, and needs a record the day teacher can use.
Virtual academy teacher
Never sits beside the student and needs to see reasoning, not only a score, before the next live session.
Principal who signs the PO
Needs a published price and a short privacy review. One teacher can start at $89 a month before the school commits.
08 FAQ
Questions schools ask before buying an online math intervention program
Running grades 3 to 5? The elementary math intervention programs page shows the fraction and place value cards, and the AI math tutor page shows the student side of a session.
What is the best online math intervention program?
There is no single best one, because online programs do different jobs. Adaptive practice software such as IXL, i-Ready or Zearn gives students the most practice minutes. Live online tutoring gives an adult who hears every step. An AI tutor like Coeducate tells the teacher why each student missed. Pick by the gap your intervention block leaves open, and check the Evidence for ESSA rating if the money is restricted.
Can math intervention be done online?
Yes, and most schools already run part of it online. Practice, tutoring and progress checks all work on a Chromebook. What does not move online on its own is the adult who notices why a student is stuck. An online program works when it sends that reason back to the teacher, or when an adult is scheduled to read its reports every week.
Is IXL a math intervention program?
IXL is adaptive practice software that many schools assign as part of intervention, not a teacher-led intervention program. Evidence for ESSA lists IXL Math with a strong rating for grades 3 to 5. It reports which skills a student misses and gives more practice on them. It does not report the reasoning behind a miss, so a teacher or a diagnostic step still has to supply that.
Is Khan Academy a good math intervention?
Khan Academy is a strong free practice and video library, and many intervention teachers use it for assignments. On its own it is self-paced, so students who are stuck tend to skip or rewatch rather than ask. Its Khanmigo tutor adds coaching on Khan content for schools at $10 per student a year on Enterprise Starter. It works best when the school already teaches from Khan Academy.
What are examples of math interventions?
Common math interventions are explicit small-group lessons from a program such as Do the Math or Math 180, concrete then pictorial then abstract representations, number line work, word-problem schema instruction, fact fluency practice, peer tutoring and one-to-one tutoring. Online options add adaptive practice software, live online tutors and AI tutors that question each student and report the misconception to the teacher.
How many minutes a week should students use an online math intervention program?
Vendors set their own targets: i-Ready asks for 30 to 49 minutes of Personalized Instruction per subject a week, and Zearn recommends about 90 minutes a week. For tutoring, the high-dosage research points to three or more sessions a week. A two or three session block of 20 to 30 minutes each is a realistic schedule for a school intervention period.
How do you monitor students in an online math intervention?
Keep your screener and your curriculum-based probe every two weeks, because those give the trend line. Then add a weekly look at what the online program reports: minutes, skills passed and, if the tool provides it, the reason behind wrong answers. Coeducate writes a dated card per session with the student's words and a CSV export the MTSS team can drop into its tracker.
How much do online math intervention programs cost?
Adaptive practice software usually costs $8 to $30 per student a year by district quote, and live tutoring about $1,200 to $2,500 per student a year. Coeducate publishes its price: $89 a month for one teacher with up to 60 students, or $3,480 a year for a school of up to 600 students, about $5.80 per student.
