Math Adventures: The Mystery of the Missing Numbers
Welcome to our exciting mystery where numbers go missing and it's up to you to find them!
Welcome students, introduce the concept of a math adventure and explain that today they will be detectives solving puzzles to find missing numbers. Emphasize that it's okay to ask for help and work as a team.
The Adventure Begins!
Our journey starts now. Follow the clues on the Math Adventure Storyboard to discover the location of the missing numbers.
Set the scene with an engaging part of the storyline. Use the storyboard material to help visualize the adventure. Explain the quest and the importance of each clue along the way.
Puzzle Exploration
Work in groups using your Missing Numbers Cards to solve puzzles. Look for clues hidden in each math problem!
Give clear instructions about puzzle exploration. Make sure groups understand that they are to use the Missing Numbers Cards to solve simple addition and subtraction problems. Remind them to discuss their strategies with group members.
Group Discussion & Wrap-Up
Let's discuss your findings and share the strategies you used to uncover the mystery of the missing numbers.
After students complete the puzzles, gather them for a group discussion. Ask each group to share how they solved the puzzles, what strategies helped them, and the fun parts of the adventure.
Congratulations, Math Detectives!
You've solved the mystery! Great job using your math skills and working as a team.

Activity
Missing Numbers Cards Activity
These cards are a central component of our math adventure. Each card contains an addition or subtraction problem where one number is missing. Students will use these cards during the interactive puzzle exploration section to fill in the missing numbers and solve the equations.
How to Use the Cards
- Group Work: Divide the class into small groups. Each group receives a set of Missing Numbers Cards.
- Discussion: In your groups, discuss the steps needed to solve each problem. For example, if a card shows "4 + __ = 9", your group can work together to determine what number fits in the blank.
- Problem Solving: Write down or verbalize your thought process as you solve each card. Explain to your group why a certain number completes the problem.
- Share Your Clue: Once a group finishes a set of cards, they will share their solutions and reasoning in the group discussion to help everyone uncover the mystery of the missing numbers.
Sample Prompt for Students
- Prompt: "Look at the Missing Numbers Card with the equation: 7 - __ = 3. How do you determine the missing number? Write down the steps you take to solve this problem."
Follow-Up Questions
- How did you decide which number fits in the blank on your card?
- What are some strategies you used to check your work?
- Can you create your own Missing Numbers Card and challenge a friend to solve it?
These questions are designed to stimulate critical thinking and help ensure that you understand the arithmetic process behind each problem. Enjoy the adventure and work together to solve the mystery!
