Unlocking the Mystery: The Code of Mathematics

Introduction to the Lesson

Welcome to today's lesson, where we will embark on an exciting journey into the world of mathematics! To ignite your curiosity and set the stage, we are going to start with a mysterious riddle that requires your mathematical prowess and logical reasoning to solve.

The Riddle

Imagine this: A treasure chest is locked, and it can only be opened by solving a clever riddle. The inscription reads:

"I am a two-digit number. My tens digit is three times my units digit. If you reverse my digits, I become 27 less than my original number. What number am I?"

Your Mission

1. Form small groups of 3-4 students to discuss the riddle and devise strategies to crack the code.
2. Use your knowledge of algebra and number properties to represent the digits mathematically.
3. Share your thoughts on how you might approach solving this riddle. Write down any equations or ideas on the whiteboard.

Let's Dive Deeper!

Once you have discussed the riddle in your groups, we will come together to analyze the strategies you've come up with. From there, we'll introduce key concepts related to two-digit numbers, algebraic expressions, and methods for solving equations.

Conclusion

By the end of our lesson, not only will you unlock the mystery of the riddle, but you'll also have enhanced your mathematical skills! Are you ready to crack the code? Let’s get started!
