ObjectivesStudents will analyze evidence to
solve mysteriesStudents will create an original
mystery story Students will construct logical
reasoning grids Students will use skills of
deduction to solve their classmates’ mysteries

Thinking Skills
Combining & summarizing information
Solving logic puzzles Making inferences Sorting & organizing clues Analyzing evidence Using deductive reasoning to
eliminate possibilities Questioning Distinguishing between fact &
opinion
Contrasting viewpoints Making predictions Supporting conclusions Differentiating between
relevant & irrelevant information
Evaluating sources Observing Validating syllogisms Sequencing events Recognizing relationships

How Have You Used Mysteries? What mystery activities have you
tried in your classroom?What worked well?What obstacles did you
encounter?

Logical ReasoningAfter students master each, they can create their own!Relationships: group characteristicsSequential reasoningAll statementsNo statements, reversals, & other negativesAnalogiesLogic DiagramsSyllogisms:
◦ Premises◦ Valid & invalid conclusions
If-then statementsDeduction: grids or matrices
◦ Try “Pizza Party”, “Spring Bulbs”, & “The Zoo Trip”

Solving MysteriesListening: Mini-mysteries on CDReading: whole group, partners, individualUnderlining or highlighting:
◦Clue phrases, important details, evidence, & suspicious behavior
◦Numbers: times, money, sequencesTaking notes: collecting clues & evidence
Students can use plastic magnifying glasses to get into the character of detective!

Create a Logic PuzzleList 4-8 suspects (clearly male/female names)Choose a culpritList 5 facial characteristics: beard, mustache,
scar, mole, etc.Write clues deducing which characteristic
matches each suspect:◦Mary does NOT have a mole.◦Betty has NEVER had stitches.
Proofread: Can a colleague solve your mystery?Revise: Add clues or correct clues to match
solution

Writing a Mystery StoryWhat happened? To whom? Where? Why?
Setting: crime scene(s)◦ Written description ◦ Crime scene sketch
Characters: ◦ Culprit◦ Other suspects◦ Victim
Plot: ◦ Clues
Detailed action (from which to infer clues) Dialogue (including questions & lies) Evidence (witness observations, thread, candy wrapper, receipt, etc.)
◦ Crime/Mystery- NONVIOLENT, missing/secret/mixed-up Motivation (how each suspect benefits from the crime) Opportunity (timing & location)
Proofreading: Can the teacher & your classmates solve the mystery?
Revising to add clues or correct clues to match solution

More Mystery IdeasCreate a “real” crime scene in your
classroom using props as evidenceTake a field trip to attend LASM Crime
Scene Investigation (CSI) classInvite a guest speaker police detective or
private investigatorHave students write a script & film a
mystery movie or perform a mystery puppet show
How would you adapt these mystery activities for your class?
