The complete Trellis Tier 1 menu — 46 research-based interventions, each mapped to CA MTSS domains, UDL, and High-Leverage Practices, and documentable in five seconds during instruction.
Who each intervention serves
ALL All students
EL English learners
SEL Social-emotional
SPED Special ed / IEP
ADV Advanced
Behavioral
All behavioral interventions
01
Behavior Reflection
SELSPED
Structured two-question prompt: what happened + what would you do differently — building accountability without escalation.
Log as Behavioral > Nonverbal Redirection. Note whether student responded to the signal.
Evidence to look for
Student self-corrects within 10–20 seconds. Instruction continues uninterrupted.
Notes
EL: Nonverbal redirection removes language demand entirely — particularly effective for ELs. Signal must be established and practiced in a low-stakes moment first.
03
Peer Recognition
ALL
Teacher publicly names a specific student's contribution — building status and sense of belonging.
Log as Behavioral > Peer Recognition. Note the specific behavior or contribution named.
Evidence to look for
Student engagement increases following recognition. Peer dynamics shift toward the student.
Notes
EQUITY: If interaction counts show same students receiving recognition repeatedly, teacher is recognizing performance not growth. Prioritize students underrepresented in interaction data.
04
Positive Narration
ALL
Teacher narrates specific, observable behavior aloud — reinforcing exactly what the student is doing correctly.
Log as Behavioral > Reset Routine. Note the triggering behavior and the duration of the reset.
Evidence to look for
Student returns within expected time in a regulated state and re-engages with the learning task.
Notes
ESCALATION SIGNAL: If reset is used more than twice per week for the same student, flag for Tier 2 discussion — reset is managing symptoms, not the underlying need.
07
Self Monitoring
SELSPED
Teacher prompts student to evaluate their own behavior against an explicit standard — building the metacognitive habit of self-regulation.
Log as Instructional > Extension Challenge. Note the mastery demonstrated and the specific extension task assigned.
Evidence to look for
Student's extension response shows application to a new context — not repetition at the same cognitive level.
Notes
ADV: Extension tasks should increase cognitive demand, not volume. One problem requiring abstraction or transfer — not three more at the same level.
09
Guided Practice
ALLELSPED
Teacher works alongside student with scaffolded prompts — narrating the process, releasing responsibility incrementally as student demonstrates understanding.
Log as Instructional > Numbered Heads Together. Note whether student was prepared when their number was called.
Evidence to look for
Student engages in group discussion more actively knowing any number could be called.
Notes
TARGETED: For chronically disengaged students, assign number 1 or 2 and call early — preventing habit of waiting to see if their number comes up.
12
Peer Teaching
ALLADV
Teacher assigns a student who has demonstrated mastery to explain a concept or coach a peer — deepening the teaching student's understanding.
Research: Vygotsky / Zone of Proximal DevelopmentCA MTSS: AcademicFramework: UDL: EngagementHLP 18, 21
Implementation & documentation
Document in Trellis
Log as Instructional > Peer Teaching. Note the concept taught and the quality of explanation given.
Evidence to look for
Teaching student's debrief reveals deeper understanding — or surfaces a gap not visible before.
Notes
ADV: Peer teaching is more cognitively demanding than completing the task independently — requires holding the entire conceptual structure in mind while adjusting to the listener.
13
Quick Write
ALLADV
Teacher directs student to write a focused response to a specific prompt for 2–3 minutes — externalizing thinking and generating written evidence.
Log as Instructional > Retrieval Practice. Note what was tested and which elements were recalled accurately versus not.
Evidence to look for
Student retrieves target content. Any gaps identify exactly what needs brief reteaching before new content is introduced.
Notes
FRAMING: Present as 'let's see what your brain has locked in' — not a test. Same learning benefit without performance anxiety.
15
Strategic Questioning
ALLELSEL
Teacher poses a single question calibrated to this student's current understanding — meeting them where they are and extending thinking one step further.
Research: John HattieCA MTSS: AcademicFramework: UDL: RepresentationHLP 12
Implementation & documentation
Document in Trellis
Log as Instructional > Strategic Questioning. Note the question type used (recall / explanation / application / analysis / evaluation).
Evidence to look for
Student produces a response one cognitive level above their typical entry point.
Notes
EL: Pair strategic question with a sentence frame ('I think ___ because ___') — preserves cognitive demand while reducing language production barrier.
16
Student Conference
ALLSELSPED
Brief, structured 1:1 conversation during independent work — focused on where the student is, what they understand, and what their next step is.
Log as Instructional > Think Ink Pair Square. Note whether student contributed in pair phase and in square phase.
Evidence to look for
Student's written response before pairing is more fully developed than a typical unprompted oral response.
Notes
EL: Individual writing step is especially valuable — allows time to organize ideas before social pressure of partner discussion. Allow writing in home language first.
18
Think Pair Share
ALLELSEL
Teacher directs student to discuss a specific question with a designated partner — providing structured, lower-stakes verbal processing before whole-class response.
Log as Instructional > Think Pair Share. Note whether student was sharer or listener, and the quality of the response shared.
Evidence to look for
Student shares a more complete or accurate response after paired discussion than they would have given cold-called.
Notes
EL: Allow discussion in home language first if a language partner is available, then ask student to share in English.
Academic: Scaffolding
19
Academic Language Prompt
ALLEL
When student uses informal language, teacher redirects to domain vocabulary using a sentence frame — building academic register through in-moment practice.
Log as Instructional > Academic Language Prompt. Note the informal language used and the academic term redirected to.
Evidence to look for
Student restates the concept using academic vocabulary. Subsequent written responses use the domain term correctly.
Notes
EL PRIORITY: Never frame informal language as wrong — frame academic language as the tool required for this context. Validate home language first, then bridge.
20
Collaborative Annotation
ELADV
Student is paired with a partner to annotate a shared text together — building meaning through discussion and reducing cognitive and language demands.
Log as Instructional > Explicit Instruction. Note which step the student mastered and which was the sticking point.
Evidence to look for
Student completes the identified step independently after explicit instruction on that step.
Notes
NOT THIS: re-explaining the concept in different words. Explicit instruction changes the structure — steps must be discrete, sequential, and individually confirmed.
22
Flexible Grouping
ALLSPED
Teacher reassigns student to a different group based on specific demands of the current task — purposeful, temporary regrouping, not fixed ability grouping.
Log as Instructional > Flexible Grouping. Note the reason for regrouping and the composition of the new group.
Evidence to look for
Student's engagement and output in the new grouping exceeds what was produced in the original group for this task type.
Notes
SPED: For students with IEP or 504 accommodations, flexible grouping may be specified in the plan. Document whether the decision aligns with the accommodation.
23
Modeling
ALLELSPED
Teacher explicitly demonstrates the skill or thinking process — showing how to do it, not just telling, before expecting independent execution.
Log as Instructional > Modeling. Note what was modeled and which step the student stalled on during first independent attempt.
Evidence to look for
Student's first independent attempt reflects the structure demonstrated in the model — particularly the decision-making steps.
Notes
vs. GUIDED PRACTICE: Use modeling when student has no mental model of how to approach. Use guided practice when student has a partial model but needs support.
24
Schema Activation
ALLEL
Teacher connects new content to something student already knows — activating existing mental frameworks to give the new concept a place to attach.
Log as Instructional > Schema Activation. Note what prior knowledge was activated and how it was connected to the new concept.
Evidence to look for
Student's response shows integration with prior knowledge — they make connections rather than treating new content as isolated information.
Notes
EL: Prior knowledge may exist in home language or from different cultural context. Ask: 'Do you know a word for this in [home language]?' — build the bridge from there.
25
Sentence Frames
ALLELSPED
Teacher provides a partially completed sentence structure to support student in producing academic oral or written language at a higher level.
Research: CA ELD Standards / Scaffolding ResearchCA MTSS: AcademicFramework: UDL: Representation · CA ELDHLP 15
Implementation & documentation
Document in Trellis
Log as Instructional > Sentence Frame. Note the frame provided and whether the student produced a response using it.
Evidence to look for
Student produces a grammatically complete, content-accurate response at a complexity level above what they produce without the scaffold.
Notes
EL PRIORITY: CA ELD Tier 2 and Tier 3 vocabulary scaffold. Frame level should match ELD proficiency — more complete for emerging, more open slots for expanding/bridging.
26
Think Aloud
ELSPED
Teacher verbalizes the internal thinking process used to work through a task — making invisible cognitive steps visible to the student.
Log as Instructional > Think Aloud. Note whether student was able to replicate the narrated thinking process on the parallel task.
Evidence to look for
Student verbalizes thinking with increasing specificity and accuracy over multiple interactions.
Notes
EL: The think aloud externalizes academic language patterns — EL students hear how proficient readers and thinkers talk about text and tasks.
27
Visual Walkthrough
ELSPED
Teacher guides student through a visual representation of the concept — diagram, graphic organizer, or illustration — using the visual as primary explanatory vehicle.
Log as Instructional > Visual Walkthrough. Note which visual was used and which features were explained.
Evidence to look for
Student can point to or explain features of the concept using the visual without teacher prompting. Student references visual independently.
Notes
EL: Walkthrough should use minimal complex language — point, label, demonstrate. Label the visual in both English and student's home language where possible.
28
Worked Examples
ELSPED
Teacher provides a fully completed example of the task type — reducing cognitive load by allowing student to study the model before attempting independently.
Log as Instructional > Worked Examples. Note the specific feature you directed the student to examine.
Evidence to look for
Student's next attempt shows structural alignment with the model — organization, format, or content follows the pattern.
Notes
EL: Worked examples reduce language demands by making task structure visible. Choose examples with clear visual organization that communicates structure beyond the text.
Academic: Formative
29
Hinge Question
ALLSPED
Single pivotal question designed to determine whether student is ready to move forward or needs reteaching — only answerable if student truly understands the core concept.
Log as Instructional > Hinge Question. Use 5-Color to record understanding level. If incorrect: note the specific misconception the answer revealed.
Evidence to look for
Teacher has a clear, binary, actionable decision: student understands the hinge concept or does not.
Notes
NOT A REVIEW QUESTION: A hinge question tests the single concept the lesson depends on. If student misses it, the rest of the lesson won't make sense.
30
Intentional Wait Time
ALLELSPED
Teacher extends think time beyond the typical 0.9-second average — signaling that the student's response is expected and that processing time is valued.
Research: Mary Budd RoweCA MTSS: AcademicFramework: UDL: EngagementHLP 18
Implementation & documentation
Document in Trellis
Log as Instructional > Intentional Wait Time. Note whether the extended wait produced a response and the quality of that response.
Evidence to look for
Student produces a response in the extended window that they would not have produced in the standard window.
Notes
RESEARCH: Average teacher wait time is 0.9 seconds. EL students need significantly more processing time — extending to 5–7 seconds produces measurably richer responses.
31
Misconception Correction
ALLELSPED
Teacher directly addresses a specific wrong mental model revealed in student's response — targeting the exact misconception, not re-explaining the whole concept.
Log as Instructional > Misconception Correction. Record the specific misconception addressed and whether correction was successful.
Evidence to look for
Student produces a correct response to a parallel question after the correction. Same misconception does not reappear in subsequent written work.
Notes
IMPORTANT: Different wrong answers reveal different mental models — identify the model before correcting. Surface-only correction will resurface.
32
Muddiest Point
ALLSPED
Student identifies the single most confusing element of the current lesson — giving teacher precise, student-generated data on where understanding breaks down.
Log as Instructional > Muddiest Point. Record what the student identified as their muddiest point.
Evidence to look for
Student names a specific concept, step, vocabulary term, or connection — not a vague 'I don't get it.' Specificity is itself a measure of metacognitive development.
Notes
FRAMING: 'Do you have any questions?' produces silence. 'What's the muddiest thing?' signals that confusion is expected and naming it is a competency.
33
One Minute Paper
ALLADV
Student writes responses to two prompts — what did I learn today and what is one question I still have — generating written evidence of understanding in under two minutes.
Log as Instructional > One Minute Paper. Record 5-Color based on 'what I learned' response. Note the remaining question.
Evidence to look for
Student's 'what I learned' response is accurate and names the lesson's core concept — not a peripheral detail. Remaining question is specific.
Notes
ADV: Replace 'what I learned' with 'what surprised me' or 'what I would investigate further' — requires synthesis rather than recall.
34
Peer Assessment
ALLADV
Student provides or receives structured feedback from a peer using shared success criteria — developing both the skill being assessed and evaluative judgment.
Research: John HattieCA MTSS: AcademicFramework: UDL: Action & ExpressionHLP 22
Implementation & documentation
Document in Trellis
Log as Instructional > Peer Assessment. Note this student's role (assessor or assessed) and the quality of feedback given or received.
Evidence to look for
Assessor's feedback names specific elements from success criteria. Student receiving feedback makes at least one revision based on peer input — not teacher direction.
Notes
ADV: Assign advanced students as lead assessor. Evaluating another's work against criteria requires and deepens understanding of the standard.
35
Practice Testing
ALLSPED
Teacher gives student a quick oral or written test on prior content — not for a grade, but as a deliberate memory-strengthening exercise before new content.
Log as Instructional > Practice Testing. Note what was tested and the accuracy rate for this student.
Evidence to look for
Student accurately retrieves prior content. Any gaps identify exactly what needs brief reteaching before new content will stick.
Notes
FRAMING: Frame as 'let's see what your brain has locked in' — not a test. Students who experience retrieval as performance testing become anxious and accuracy drops.
36
Productive Struggle Maint.
ALLADV
Teacher intentionally withholds immediate support when student is in productive struggle — allowing difficulty to generate learning rather than rescuing prematurely.
Log as Instructional > Productive Struggle Maintenance. Note what student was attempting and how long struggle was maintained before resolution.
Evidence to look for
Student resolves task independently or identifies a specific sticking point. Over time, persistence window lengthens before student seeks support.
Notes
DIAGNOSIS FIRST: Productive struggle maintenance is not withholding help from a student who is lost. Requires accurate diagnosis — struggling with the right thing?
37
Self Assessment
ALLSPEDADV
Teacher prompts student to evaluate their own understanding against an explicit standard — building the internal feedback loop that reduces dependence on teacher confirmation.
Research: John HattieCA MTSS: AcademicFramework: UDL: Action & ExpressionHLP 14
Implementation & documentation
Document in Trellis
Log as Instructional > Self Assessment. Record student's self-rating alongside your independent observation of their actual task performance.
Evidence to look for
Over the Sprint, self-rating accuracy improves — the gap between self-rating and teacher rating narrows.
Notes
OVER TIME: Track self-ratings across sessions. Consistent under-rating may need confidence-building. Consistent over-rating may need more challenge or clearer success criteria.
38
Self Correction Prompt
ALLSPEDADV
Teacher directs student to locate and fix their own error without identifying it — building the metacognitive habit of self-monitoring during production.
Log as Instructional > Self Correction Prompt. Record the error type targeted, whether student located it independently, and whether correction was accurate.
Evidence to look for
Student locates the error type without teacher pointing to it. Reduced frequency of the same error in subsequent work.
Notes
DIFFERENTIATION — SPED: Narrow the scope ('look only at this paragraph'). ADV: Widen it ('find all instances, identify the pattern, write a rule explaining why this keeps occurring').
39
Traffic Light Signal
ALLELSPED
Students use a pre-taught simultaneous signal — red, yellow, or green — to communicate current understanding without interrupting instruction.
Log as Instructional > Traffic Light Signal. Record this student's signal color for this checkpoint.
Evidence to look for
Signal color aligns with actual performance on the subsequent task. Over time, student accurately self-signals rather than defaulting to green.
Notes
EL: Nonverbal nature removes language demand from the comprehension check — particularly valuable for ELs who understand content but lack verbal expression in English.
40
What's the Question?
ALLADV
Teacher gives student an answer and asks them to generate the question — reversing Q&A structure to require deeper understanding of conceptual relationships.
Log as Instructional > What's the Question? Note the quality of question generated — whether it reflects surface or conceptual understanding.
Evidence to look for
Student's generated question reveals understanding of the conceptual relationship, not just surface recall.
Notes
ADV: Generating the question requires holding the entire conceptual structure in mind and identifying the gap the answer fills — higher-order than answering directly.
Academic: Modified
41
Choice Boards — Offer
ELSPED
Pre-designed grid of task options allowing students to demonstrate understanding through different modalities or complexity levels. Trellis documents the choice selected.
Log as Instructional > Choice Board. Record which option was selected and whether it was directed or student-chosen.
Evidence to look for
Student's chosen task produces evidence of understanding comparable in quality to the standard task — format flexibility didn't reduce rigor.
Notes
PRE-PLANNED: Choice board must be designed and distributed before class.
42
Error Analysis — Target
ALLSPEDADV
Teacher identifies a specific error pattern and directs student to locate and correct that error type independently — building metacognitive editing skills.
Log as Instructional > Error Analysis. Record the error type targeted and whether the student located it independently.
Evidence to look for
Student locates the error type without teacher pointing to it. Reduced frequency of the same error in subsequent work.
Notes
DIFFERENTIATION — SPED: Narrow to a single paragraph. ADV: 'Find all instances, identify the pattern, and write a rule explaining why this error keeps occurring.'
43
Exit Ticket — Assign
ALLSPED
Brief written task completed at end of class generating per-student evidence of what was understood. Trellis logs the proficiency result when teacher reviews responses.
Log as Instructional > Exit Ticket. Record 5-Color proficiency after reviewing student response. Note any misconceptions revealed.
Evidence to look for
Exit ticket response reveals whether student mastered today's learning target. Teacher adjusts tomorrow's opening based on the pattern across responses.
Notes
5-COLOR ALIGNMENT: Green = fully demonstrates target. Yellow = partially accurate, one gap. Orange = some relevant content, significant gaps. Red = response does not demonstrate target.
44
Gallery Walk — Assign Stn.
ALLEL
Students rotate through posted stations responding in writing or discussion. Trellis documents starting station and engagement quality across rotation.
Research: Active LearningCA MTSS: AcademicFramework: UDL: EngagementHLP 18
Implementation & documentation
Document in Trellis
Log as Instructional > Gallery Walk. Record assigned starting station and engagement quality at each stop.
Evidence to look for
Student's written responses at stations show engagement with content — not just a name and a check mark.
Notes
PRE-PLANNED: Stations must be designed and arranged before class. Direct struggling students to scaffolded stations first.
45
Jigsaw — Assign Role
ALLEL
Students become content experts on one portion of material, then teach that content to peers in a mixed group. Trellis documents role and participation quality.
Log as Instructional > Jigsaw. Record the expert topic assigned, participation in expert group, and accuracy during peer teaching.
Evidence to look for
Student can accurately teach their expert content to peers without referring to notes.
Notes
PRE-PLANNED: Expert groups, mixed groups, and assigned content sections must be organized before class.
46
Revision Cycles — Prompt
ALLADV
Teacher returns student to prior work with a targeted, specific revision prompt — directing focused improvement in one element rather than general feedback.
Log as Instructional > Revision Cycles. Record what was flagged for revision and whether the revision was completed and accurate.
Evidence to look for
Revised work shows improvement specifically in the targeted element. Student can explain what they changed and why.
Notes
ADV: Escalate scope progressively — 'Now that the thesis is revised, check whether body paragraphs support the new thesis.' Progressive revision chains build sustained self-editing skill.
