Tier 2 math intervention programs and small group math intervention that show why each student missed
Your Tier 2 fraction group has five students who got the same item wrong for five different reasons. Coeducate tutors each one with questions while you teach the group, then names the idea that broke. Paste a student answer into the panel to see it work.
Grades 3 to 12. From $5.80 per student a year on the School plan.

The short answer
What a Tier 2 math intervention program has to do
A Tier 2 math intervention program gives small groups of students who fell below benchmark extra, explicit lessons on one shared gap, three to five times a week, with progress checked every two weeks. Coeducate is the AI tutor that runs inside that block: each student in the group works an item from the gap one to one with the tutor, and the teacher gets a card naming the misconception behind every wrong answer.
It is not a standard-protocol curriculum and not a progress monitoring probe. Schools keep both. It adds the part a group lesson cannot cover in 30 minutes: hearing every student's reasoning, not only the one who answers out loud.

01 Why Tier 2 groups stall
One fraction group with five wrong answers and five different reasons
A screener puts students in a group because they share a low score on a strand. It does not say that they share a misconception. In a typical grade 5 fraction group, one student thinks a bigger denominator makes a bigger fraction, another adds the tops and the bottoms, a third has a decimal place value gap that only looks like a fraction problem.
Teach all five the same reteach and you fix one or two of them. The other three keep the same rule, the probe stays flat, and at week eight the team cannot say why.
Student A
3/8 > 3/4
Bigger denominator means a bigger fraction
Whole-number thinking
Student B
1/2 + 1/3 = 2/5
Adds tops and adds bottoms
Operation rule, no meaning
Student C
2/3 of 12 = 4
Divides by 3 and stops
Partial procedure
Student D
0.5 < 0.25
Longer decimal is bigger
Place value
Student E
4/6 = 3/5
Subtracts one from top and bottom
Equivalence as same gap
The tutor talks with each student one at a time, asks them to explain the step, and writes the reason on a card. The adult then splits the next session by reason instead of by score. For grades 3 to 5 groups, the elementary math intervention programs page shows the place value and fraction cards in detail.
02 What schools buy for Tier 2
The four kinds of Tier 2 math intervention programs and what each one leaves out
Most Tier 2 blocks combine two of these. The honest question is which gap your current combination leaves open.

AI tutor with teacher reports
Coeducate
Gives you
One-to-one questioning for every student in the group at once, and a named misconception per student.

$3,480 a year for up to 600 students
Software prices above come from public district quotes we compiled for IXL cost per student, i-Ready cost per student and Zearn cost for schools. Tutoring costs come from the high dosage tutoring page. If your team has to cite an ESSA evidence tier for the purchase, start with the research based math intervention programs list and add the tutor next to a rated program.
03 How it runs
A 30 minute small group math intervention block in three stations
-
1
10 min
Teacher table
Two or three students with the same named misconception get the reteach from Friday's cards. Explicit, with the representation your program calls for.
-
2
10 min
Tutor station
Two students each work an item from the target gap with the tutor on a laptop. It asks one question at a time and does not hand over the answer.
-
3
10 min
Practice station
The rest practice in the program or software you already own. Rotate, so every student hits all three stations twice a week.
04 Example output
What the card says about Student A from the fraction group
The item and what the student wrote
Which is bigger, 3/8 or 3/4? "3/8, because 8 is bigger than 4."
The adaptive practice report for this student said "comparing fractions, 40 percent". The card says why, in the student's words, and gives a reteach that starts from the size of the pieces, not from a rule. Three weeks of these cards are what the team reads at the six week review.
Session evidence card, grade 5, comparing fractions
Fixed exampleDiagnosis
Reads a larger denominator as a larger fraction
The student compares the denominators as whole numbers. Asked to draw 1/8 and 1/4 of the same bar, the student drew them correctly and said the eighth looked smaller, then went back to the rule on the next item. The picture is right and the rule overrides it, so this is a whole-number habit, not a missing skill.
Next tutoring move / hint only
You drew 1/8 smaller than 1/4. So which is bigger, three of the small pieces or three of the big pieces?
Skill mastery read
Comparing fractions
Not yetChose 3/8 over 3/4 because 8 is bigger than 4.
Unit fractions
DevelopingDrew 1/8 and 1/4 of a bar correctly, did not use the drawing to compare.
Fractions on a number line
DevelopingPlaced 1/2 correctly, put 3/8 to the right of 3/4.
Explaining a step in words
SecureStated the rule clearly, which is what made the error visible.
Teacher note
This student needs a different reteach from the student who adds numerators and denominators. Group them separately on Monday.
Reteach in 5 minutes
Same number of pieces, different piece size
- Fold two equal strips into fourths and eighths and shade three pieces of each.
- Ask which shaded part is longer before naming either fraction.
- Give three pairs with equal numerators and ask for the reason before the answer.
05 The decision cycle
A Tier 2 math intervention cycle from screener to exit or Tier 3
Week 0
Screen and group
Fall, winter or spring screener. Students below the cut score are grouped by strand.
Weeks 1 to 2
First tutor sessions
Each student works two or three items with the tutor. The cards split the group by reason, not by score.
Weeks 2 to 6
Teach and monitor
Program lessons at the teacher table, tutor sessions twice a week, a probe every two weeks.
Week 6 to 8
Team review
Probe trend plus dated cards. The team sees who is moving and, for the rest, which idea keeps failing.
Week 8 to 12
Exit, adjust or Tier 3
Students at goal return to Tier 1. Flat trends get a changed plan or move to intensive support.
When a student moves up, the cards go with them. The Tier 3 math intervention programs page shows how the same record feeds the data-based individualization meeting, and the MTSS progress monitoring software page shows the CSV export next to your probe graph.
06 Being straight about it
When this is the wrong Tier 2 math program to buy
- Your groups have no lessons yet. Tier 2 needs explicit instruction from an adult. Buy or adopt a standard-protocol program first and add the tutor as the diagnostic layer.
- The purchase must carry an ESSA tier on its own. Coeducate has no efficacy study. Fund a rated program with the restricted money and put the tutor on a general line.
- The students are in kindergarten to grade 2. Early Tier 2 math is counting and quantity with objects. The tutor reads written reasoning, so it starts at grade 3.
- You need a screener or a probe score. The tutor does not produce a normed score or a rate of improvement. Keep the screener and the curriculum-based measures you already use.
07 Who uses it
Built for the people who run Tier 2 math groups
Math interventionist
Runs six groups a day across three grades. The cards sort each group by reason before Monday.
Classroom teacher in a WIN block
Teaches one group while the others rotate. The tutor station is the second adult in the room.
MTSS coordinator
Chairs the six week review and wants a reason on the table, not only a trend line. CSV export goes into the team tracker.
Principal who signs the PO
Needs a published price and a privacy posture that survives review. See AI tutor for schools pricing and the student data and COPPA page.
08 FAQ
Questions teams ask before buying a Tier 2 math intervention program
Running groups in grades 9 and up? The high school math intervention programs page covers Algebra 1 support, and math intervention software covers the middle grades.
What are Tier 2 interventions in math?
Tier 2 math interventions are targeted, small-group lessons given on top of core math class to students who scored below benchmark on a screener. A group of about three to six students meets for 20 to 40 minutes, three to five days a week, works on one shared gap such as fractions or place value, and is progress monitored every two to four weeks.
What are examples of Tier 2 math interventions?
Common examples are a standard-protocol program taught to a small group (Fraction Face-Off!, Do the Math, Bridges Intervention, Math 180), explicit lessons with concrete then pictorial then abstract representations, number line work, word-problem schema instruction and ten minutes of fluency practice per session. Adaptive practice software and tutoring are often layered on as extra practice.
How long should Tier 2 interventions last?
Most MTSS handbooks plan Tier 2 in cycles of six to twelve weeks, with a review at about six to eight weeks once there are enough progress data points to see a trend. Students who reach the goal exit to Tier 1. Students with a flat trend get a changed plan or move to Tier 3. Sessions inside the cycle usually run 20 to 40 minutes.
How many students should be in a Tier 2 intervention group?
Three to six students is the usual Tier 2 group, and some schools run in-class groups of up to eight. Smaller groups let the adult hear each student's reasoning. The cost of a larger group is that students with different misconceptions get the same lesson, which is why the reason behind each wrong answer matters more as the group grows.
How often should Tier 2 students be progress monitored?
Every two weeks is the most common standard for Tier 2, and some districts accept monthly. Weekly monitoring is usually reserved for Tier 3. A curriculum-based measure on a fixed schedule gives the trend line the team uses at the six to eight week review. It shows whether a student is moving, not why they are stuck.
Who provides Tier 2 interventions?
Tier 2 math is usually delivered by a math interventionist, a classroom teacher during a WIN or intervention block, a trained paraprofessional or a tutor following a standard protocol. The school's MTSS team decides who teaches each group. Whoever delivers it needs the screener results, the program materials and a simple way to log sessions and progress.
Is IXL a Tier 2 intervention?
IXL is adaptive practice software, not a teacher-led Tier 2 program, though many schools assign it as extra practice in a Tier 2 block. Evidence for ESSA lists IXL Math with a strong rating for grades 3 to 5. It reports which skills a student misses, not the reasoning behind the miss, so groups still need an adult or a diagnostic step.
How much do Tier 2 math intervention programs cost?
Kit-based programs are priced per teacher or per kit and most software is licensed per student per year by quote, often $8 to $30 per student. Coeducate publishes its price: $89 a month for one teacher with up to 60 students and $3,480 a year for a school of up to 600 students, about $5.80 per student.
