Lesson Plan: The Mimic's Mathematical Mayhem

Materials Needed

• Pencil and paper
• A printout of a simple grid (or graph paper)
• A small token or counter (like a button or coin) to represent an animatronic
• Optional: A calculator (for checking work, not for initial problem-solving)
• Optional: Coloured pencils or markers
• A clock or timer to add to the atmosphere

Lesson Details

• Subject: Mathematics
• Year Level: Year 3 (Age 8)
• Theme: Five Nights at Freddy’s - Secret of the Mimic
• Curriculum Link: NSW Mathematics K-10 Syllabus - MAO-WM-01: Develops an understanding and fluency in mathematics through exploring and connecting mathematical concepts, choosing and applying mathematical techniques to solve problems, and communicating their thinking and reasoning coherently and clearly.

1. Learning Objectives

By the end of this lesson, the student will be able to:

• Apply mathematical concepts (time, patterns, addition/subtraction, simple multiplication) to solve multi-step problems.
• Choose an appropriate strategy to solve a given problem and explain why they chose it.
• Clearly communicate their mathematical thinking and reasoning, both verbally and in writing.
• Design a unique mathematical puzzle that demonstrates their understanding of a concept.

2. Lesson Procedure & Instructional Strategies

Part 1: The Night Shift Briefing (5 minutes)

Instructional Strategy: Narrative-Based Introduction

Teacher's Role: Set the scene to engage the student. Say something like:

"Welcome to your new job at the Pizzaplex. It's midnight, and things are... strange. The lead technician left behind some notes about the 'Mimic' animatronic. To survive until 6 AM and figure out its secrets, you'll need to solve a series of puzzles it has left behind. Each puzzle you solve keeps the systems stable and gets you closer to the truth. Are you ready?"

Part 2: Mission 1 - Power Grid Panic (10 minutes)

Instructional Strategy: Problem-Solving & Direct Application

Task: Present this problem to the student:

"The security office starts with 100% power at midnight. Every hour, the lights and cameras use up 12% of the power. Will you have enough power to last until 6 AM? How much power will be left over, or how much extra power would you need?"

Guiding Questions (to encourage communication):

• "How many hours are there between midnight and 6 AM?"
• "How could you figure out the total power used? Could you use addition? Is there a faster way?" (Guiding towards multiplication: 6 hours x 12% power).
• "Explain your steps to me as you do them. Why did you decide to add/multiply first?"

Part 3: Mission 2 - Tracking the Animatronic (15 minutes)

Instructional Strategy: Kinesthetic & Visual Learning (Hands-on)

Task: Give the student the grid paper and a token.

"The Mimic isn't moving randomly. It follows a secret pattern on the building's floor grid. I've tracked its first few moves. Starting at square one, it moves: 3 squares right, 2 squares up, 3 squares right, 2 squares up."

1. Ask the student to place the token on a starting square and follow the path.
2. The Problem: "What is the pattern? Where will the Mimic be after it makes four more moves following this same pattern?"
3. Ask the student to draw the path and circle the final location.

Guiding Questions:

• "What part of the movement repeats?"
• "How did you use the grid to help you visualize the path?"
• "Can you describe the pattern to me in your own words?"

Part 4: Mission 3 - Your Turn to Design (15 minutes) - KEY CREATIVE TASK

Instructional Strategy: Creative Application & Peer Teaching

Task: Now, challenge the student to become the puzzle master.

"Excellent work, you've almost made it to 6 AM! For the final challenge, you need to create your own FNAF-themed math puzzle to lock down the Mimic for good. It can be about anything – parts and service, security doors, pizza ingredients, anything! Your puzzle must have a clear question and a clear answer."

Requirements for the student:

1. Create a Story Problem: Write a short, FNAF-themed math problem on a piece of paper.
2. Solve Your Own Problem: On the back, write down the answer and, most importantly, write down the steps needed to solve it.
3. Present the Puzzle: Give the puzzle to the teacher/parent to solve.
4. Explain the Solution: After the teacher solves it, the student must explain their solution steps, acting as the expert.

Part 5: Conclusion - You Survived! (5 minutes)

Instructional Strategy: Reflective Discussion

Teacher's Role: Congratulate the student on "surviving the night." Discuss the lesson.

• "Which puzzle was the most challenging? Why?"
• "What mathematical skill did you feel most confident using today?"
• "When you created your own puzzle, how did you decide what math to use?"

3. Differentiation and Inclusivity

• For Extra Support:
  • In Mission 1, use simpler numbers (e.g., 10% power drain per hour). Provide a 100-chart for visual subtraction.
  • In Mission 2, use a simpler pattern (e.g., 2 squares right, 1 square up) and ask for fewer future moves.
  • For the creative task, provide sentence starters like "Freddy needs to deliver pizzas..." or "You have 20Faz-Coins and need to buy..."
• For Extension/Challenge:
  • In Mission 1, add a variable: "If you close a door, you use an extra 5% power per hour. If a door is closed for 2 hours, will you still have enough power?"
  • In Mission 2, use a more complex, multi-stage pattern or introduce coordinate-based movement (e.g., "Move from (2,1) to (5,1)").
  • For the creative task, challenge the student to create a multi-step problem that requires at least two different operations (e.g., multiplication and then subtraction).

4. Assessment Methods

• Formative (Ongoing):
  • Observation: Watch how the student approaches each problem. Do they hesitate? Do they dive right in?
  • Questioning: Use the guiding questions listed in each mission to assess the student's thought process in real-time. Their ability to explain *why* they are taking a certain step is a direct measure of MAO-WM-01.
• Summative (End of Lesson):
  • Student-Created Puzzle: This is the primary assessment tool. Evaluate it based on:
    1. Clarity: Is the problem easy to understand?
    2. Correctness: Is the student's solution and answer key accurate?
    3. Reasoning: How well does the student explain the steps to solve their own puzzle? This demonstrates their depth of understanding and ability to communicate mathematically.
