Lesson Plan

Investigation Blueprint

Guide a 4th grade student through a structured 30-minute Behavior Detective session to collect behavior data, analyze patterns, and co-create targeted intervention steps.

This lesson empowers students to understand and manage their own behaviors by systematically collecting data, identifying triggers, and developing personalized strategies—fostering self-awareness and positive change.

Audience

4th Grade Student

Time

30 minutes

Approach

Structured data collection and collaborative problem-solving

Prep

Teacher Preparation

10 minutes

Step 1

Introduction & Goal Setting

5 minutes

  • Greet the student and build rapport
  • Explain the session’s purpose: collect behavior clues, identify patterns, and co-create an action plan
  • Share today’s objectives: data collection, pattern identification, intervention planning
  • Emphasize confidentiality and positive intent

Step 2

Data Review & Clue Collection

7 minutes

  • Display the Clue Collection Slide Deck
  • Prompt the student to recall recent instances of the target behavior
  • Record contextual details (when, where, who, what happened) as “clues” on the slides
  • Encourage descriptive, nonjudgmental language

Step 3

Behavior Diary Setup

5 minutes

  • Distribute the Behavior Diary Worksheet
  • Guide the student to select one or two specific behaviors to monitor
  • Model how to log date, time, antecedents, behavior, and consequences
  • Agree on a daily or per-period logging frequency

Step 4

Hypothesis Huddle

7 minutes

  • Use the Hypothesis Huddle Discussion Guide
  • Brainstorm possible triggers (antecedents) and outcomes (consequences)
  • Have the student rank their top hypotheses for why the behavior occurs
  • Validate all contributions and foster curiosity

Step 5

Evidence Evaluation

3 minutes

  • Present the Evidence Evaluation Rubric
  • Review collected clues and hypotheses
  • Have the student rate each hypothesis’s support level (strong, moderate, weak)
  • Discuss which hypothesis is best supported by the data

Step 6

Action Planning & Reflection

3 minutes

  • Co-develop 1–2 small intervention steps based on the strongest hypothesis
  • Invite the student to reflect on key insights from today’s session
  • Assign diary logging tasks and schedule the next check-in
  • Reinforce the student’s role as a behavior detective and celebrate their progress

Slide Deck

Clue Collection

Gathering and recording behavior clues to help us see patterns

Introduce the Clue Collection deck. Explain that clues are details about when, where, and how their behavior happens. Encourage curiosity and openness.

Why Collect Clues?

• Understand when and where a behavior happens
• Identify possible triggers (antecedents)
• Discover what happens afterward (consequences)
• Use data to make positive changes

Define why we collect clues. Emphasize that clues help us understand triggers and results of behaviors without judgment.

Clue Logging Template

When (date & time):
Where (location):
Who was involved:
What I did or saw:
What happened next (outcome):

Walk the student through each field. Model filling in a clue step by step.

Example Clue

When: Monday at 10:15 AM
Where: Math class
Who: Me and Ms. Lee
What I did: Tapped my pencil repeatedly
What happened next: Ms. Lee asked me to stop; classmates giggled

Show this example to illustrate clear, factual descriptions. Point out how each field is complete.

Your Turn: Log a Clue

When (date & time):
Where (location):
Who was involved:
What I did or saw:
What happened next (outcome):

Invite the student to fill in their own clue. Provide positive prompts and help as needed.

Next Steps

• Review today’s clues and pick 1–2 patterns to explore
• Bring these clues to our Hypothesis Huddle session
• Use the Behavior Diary to log daily clues
• Remember: you’re the detective—every detail counts!

Summarize and transition to next lesson steps. Remind the student to record at least one more clue before you meet again.

Worksheet

Behavior Diary Worksheet

Use this diary to log each instance of your target behavior. Be as detailed as you can!

Log Entry 1

Date: ____________________________



Time: ____________________________



Location: _________________________



Antecedent (What happened just before?):






Behavior (What you did or saw?):






Consequence (What happened next?):






Log Entry 2

Date: ____________________________



Time: ____________________________



Location: _________________________



Antecedent (What happened just before?):






Behavior (What you did or saw?):






Consequence (What happened next?):






Reflection Prompts

Answer these questions after completing your diary entries:

  1. What did I notice about my behavior today?










  2. What seemed to trigger my behavior?










  3. How did I feel after it happened?










  4. What could I try next time to change this pattern?










Keep your diary entries up to date and bring this worksheet to each session!

(For teacher reference: use this alongside the Evidence Evaluation Rubric and our next Hypothesis Huddle Discussion Guide.)

Discussion

Hypothesis Huddle Discussion Guide

Session Length: 7 minutes
Goal: Brainstorm and evaluate possible reasons (hypotheses) for the target behavior using collected clues.

Materials

Steps

1. Warm-up (1 minute)

• Remind the student that they’re the detective and review one or two clues together.

2. Brainstorm Potential Triggers (2 minutes)

Question: What happened just before your behavior in the clues we collected?
• Encourage listing all possible antecedents.
• Probe: Who was there? What were you doing? How were you feeling?

Your ideas:

  1. ____________________________________________________________________





  2. ____________________________________________________________________





3. Explore Possible Outcomes (2 minutes)

Question: What tended to happen after the behavior?
• Think about how others responded and how you felt.

Your ideas:

  1. ____________________________________________________________________





  2. ____________________________________________________________________





4. Form Hypotheses (1 minute)

Combine triggers and outcomes to create “If… then…” statements.
Example: If I feel stressed during group work, then I tap my pencil because I want attention.

Your hypotheses:

  • Hypothesis 1: ___________________________________________________________










  • Hypothesis 2: ___________________________________________________________










5. Rank and Evaluate (1 minute)

Use the Evidence Evaluation Rubric to rate each hypothesis: Strong, Moderate, Weak.

HypothesisRatingNotes
Hypothesis 1__________________________________


Hypothesis 2__________________________________


6. Next Steps (Final Thoughts)

Discuss which hypothesis seems most supported and plan one small test or strategy to try before the next session.

• Test idea: ____________________________________________________________________






• When to check results: _________________________________________________________


Note: Validate every idea, encourage curiosity, and celebrate the student’s detective work!

Rubric

Evidence Evaluation Rubric

Use this rubric to rate how well the collected clues support each hypothesis. Mark each criterion as Strong, Moderate, or Weak.

CriterionStrong (3)Moderate (2)Weak (1)
Number of Clues4 or more clear, detailed clues collected2–3 clues collectedFewer than 2 clues collected
Relevance to HypothesisAll clues directly support or refute the hypothesisSome clues support or refute the hypothesisMost clues are irrelevant or unclear
Consistency Across OccurrencesClues show a clear, repeatable patternPatterns appear but with occasional inconsistenciesNo clear pattern or inconsistent clues
Level of DetailRich, specific descriptions (who, what, when, where)Some details but missing key contextDescriptions are vague or incomplete

How to use:

  1. Review each hypothesis alongside your collected clues.

  2. Rate each criterion based on the evidence.

  3. Sum the scores (3 = Strong, 2 = Moderate, 1 = Weak) to determine overall support:


    • 10–12: Strong support


    • 6–9: Moderate support


    • 4–5: Weak support

  4. Discuss which hypothesis has the strongest overall score and plan your next intervention step accordingly.
