Missing Cookies Reading Case File #1024
The Mysterious Case of the Missing Cookies
It was a quiet Saturday morning. Maya tiptoed into the kitchen, her stomach rumbling. She had been dreaming of the chocolate chip cookies her grandma baked yesterday. Grandma always hid them in the big blue cookie jar on the top shelf.
But when Maya looked, the cookie jar was open. And empty! A single trail of crumbs led from the counter, across the shiny kitchen floor, and into the living room.
Maya followed the crumbs. They stopped right at the edge of the sofa, where her little brother, Leo, was fast asleep, a suspiciously sticky smudge on his cheek. A half-eaten glass of milk sat on the coffee table beside him.

Mission Timeline
01
Engage / Connect
5 Minutes
Post objective: "I can make an inference using evidence." Prompt Think-Pair-Share on the title clues. Look for connections to text features.
02
Teach - I Do
15 Minutes
Teacher Think-Aloud: "I notice the author says... but I know... so I can infer..." Explicitly name evidence and model the anchor structure.
03
Guided Practice - We Do
20 Minutes
Underline evidence about crumbs together. Use sentence stems on the worksheet to build a collective inference. Redirect guessing to text evidence.
04
Independent Practice - You Do
15 Minutes
Students read the rest of the text and write one inference with justification. Teacher circulates to support and redirect as needed.
05
DOL / Exit Ticket
5 Minutes
Distribute Cool Down. Students write a final inference from the text with explicit evidence references.
Field Adjustments
Reteach: Small group session focusing on the anchor chart: Text Evidence + Prior Knowledge = Inference. Use simplified chunks of text.
Extension: Challenge students to find "Deep Clues" (tricky inferences) or use the Deeper Inferences Journal for complex analysis.
Debrief Notes
• What % of students met mastery on DOL?
• Identify common misconceptions (e.g., guessing vs. inferring).
• Plan strategy for next session based on worksheet results.

Phase 1
Engage & Connect (5 min)
Teacher Says: "Good morning, future detectives! Take a look at our student-friendly objective for today: I can make an inference using evidence from the text. Our big goal is to make inferences by combining what the text says with what we already know. This is a superpower that helps us understand stories and information even better!"
"Now, let's get our brains warmed up. Our focus text today is called 'The Mysterious Case of the Missing Cookies' . Just by looking at that title, what do you think the reader might need to figure out that the author does not say directly? Turn and Talk with your partner for about two minutes. Share one idea when I call on you!"
Look-Fors:
Students predicting someone ate them or they were stolen.
Connections between the word "Mysterious" and the need for investigation.
Phase 2
Teach – I Do (10–15 min)
Teacher Says: "Alright, let's put on our detective hats. I'm going to show you exactly how I, as a super-sleuth reader, make an inference. This is called a 'think-aloud'. You'll hear what's going on inside my head."
*(Display Slide 3 or write on the board)*
"I'm looking at the first part of our story. The author says, 'Maya tiptoed into the kitchen, her stomach rumbling. She had been dreaming of the chocolate chip cookies her grandma baked yesterday.' Hmm. The author also says, 'But when Maya looked, the cookie jar was open. And empty!'"
"So, I notice the author says the cookie jar was open and empty. The author does not say who ate the cookies. But I know that Grandma usually hides delicious cookies in that jar, and if it's open and empty, it's very likely someone took them. When I combine the text with what I know, I can infer that someone has eaten all of Grandma's chocolate chip cookies."

Inference: Someone secretly ate the cookies.

Case #1024: Missing Cookies Investigation
Part 1: Guided Practice (We Do)
The text says:
"A single trail of crumbs led from the counter, across the shiny kitchen floor, and into the living room."
I know:
Crumbs are often left behind when someone eats messy food, like cookies, and then walks away while still eating or with crumbs on them.
I can infer:
The person who took the cookies walked from the kitchen to the living room, leaving a trail of crumbs behind them.
Part 2: Independent Practice (You Do)
My Inference:
Leo, Maya's little brother, is the one who ate the missing cookies.
My Evidence:
"They stopped right at the edge of the sofa, where her little brother, Leo, was fast asleep, a suspiciously sticky smudge on his cheek. A half-eaten glass of milk sat on the coffee table beside him."
Justification:
The crumbs lead directly to where Leo is sleeping. The "sticky smudge" is likely chocolate or cookie remains, and the milk is a classic pairing with cookies. All these clues pointing to one person allow us to infer Leo is the culprit.
Note: Student inferences may vary in wording, but they should include both specific text evidence and a logical connection to their own knowledge.

Post-Investigation Discussion Guide
Opening Statement
"Welcome, master inference detectives! Today, we've been practicing a super important skill: making inferences. We know that inferences are smart guesses we make by combining what the text says with what we already know. Now, let's share some of our findings and strategies."
1. Opening the Case
"Thinking about the story, what was one of the first inferences you were able to make? What specific text evidence helped you?"
Expected answer: Someone ate the cookies because the jar was empty.
"What prior knowledge did you use? If you inferred someone ate the cookies, what do you already know about empty jars and crumbs?"
Expected answer: Cookies don't disappear on their own; crumbs mean someone was eating.
2. Challenging Clues
"Was there any part that was tricky to infer? What made it difficult?"
Goal: Identify where text evidence might have been vague or where students didn't have enough background knowledge.
"Can someone share a moment when they had to stop guessing and really look for evidence? Why is it important not to just guess?"
Goal: Distinguish between a "blind guess" and a "text-based inference."
3. Real-World Inferences
"We make inferences all the time! Can you think of a time outside of school where you had to make an inference? About a friend's mood? Or what your pet wanted?"
Goal: Connect classroom skills to everyday life observation and social-emotional learning.
"Great job sharing your detective insights! Remember, the more we practice combining text clues with our own knowledge, the better we'll become at understanding the world around us."

Observational Evidence Activity
Active Learning
Objective
Students will practice making inferences about actions and emotions by observing non-verbal cues.
Tactical Briefing
Divide class into groups of 4-5.
Volunteers draw a scenario slip.
Act out the scenario silently.
Group members make an inference and justify it using observed evidence.
The Goal
"Detectives, sometimes the best clues aren't words, but actions! Combine what you see with what you know to crack the code."
Scenario Slips (Print & Cut)
Pretending to shiver and rub your arms
Stomping your feet and crossing your arms with a frown
Tiptoeing quietly and looking around nervously
Holding your stomach and making a pained face
Yawning widely and stretching, then looking at a clock
Searching frantically for something, looking under chairs
Smiling widely, jumping up and down, and giving a thumbs-up
Covering your mouth and looking surprised or shocked
Holding an imaginary umbrella and looking up at the sky
Making a loud crunching sound and pointing to an empty wrapper
Debrief Questions:
"How was this activity similar to making inferences when we read? What kind of 'evidence' did we use? How did your 'prior knowledge' of human behavior help you?"

Classroom Assessment Guide
1
Correct Answer:
Maria is upset or disappointed about her test results.
Detective Reasoning: Slumped shoulders, avoiding eye contact with the test, and "sinking" into a chair are common body language indicators of disappointment or sadness.
2
Correct Answer:
The dog hears someone arriving.
Detective Reasoning: Perked ears indicate listening; wagging tails and excited barking at a door are standard behaviors for a dog greeting someone.
3
Open Response Exemplar:
"A severe storm is happening. My evidence is that the lights went out, the wind is howling, and rain is hitting the windows. I know that strong storms can cause power outages and have loud wind and rain."
Grading Criteria:
Identifies a storm or bad weather.
Cites at least one piece of evidence (lights, wind, or rain).
Connects evidence to prior knowledge about storms.
