Lesson Kick-off: Place Value Adventure

Setting the Scene

Welcome to the world of maths, where numbers come alive! Today, we're going on an exciting adventure into the mysterious land of place value! Before we dive into our lesson, let's spark our imaginations with a fun activity.

The Number Detective Challenge

Imagine you're a number detective assigned to solve a mystery! Each of you will receive a secret number code that holds the key to your mission. This number isn't just any number; it has different places that tell us how much each digit is worth.

Your Mission

1. Gather Your Tools: Each detective will need a piece of paper and a pencil.
2. Receive Your Code: Here’s your number code! Can you figure it out?
   • Code: 4, 7, 2, 3
3. Decode the Number:
   • Write down the place value for each digit. Remember:
     • The 4 is in the thousands place.
     • The 7 is in the hundreds place.
     • The 2 is in the tens place.
     • The 3 is in the ones place.

Challenge Questions

To complete your detective work, answer these questions:

• What is the value of the number code?
• If you swapped the 7 and 2, what new number would you have?
• How would the value change if you replaced the 3 with a 5?

Group Share

Once you’ve cracked the code, share your findings with your partner! Discuss how you figured out each digit's worth.

Conclusion

We'll regroup after this exciting exercise and share our discoveries. Remember, every digit has a story to tell based on its place value. Ready to solve the mystery? On your marks, get set, decode!
