Let's Explore Place Value!

Introduction

Good morning, class! Today, we are going to embark on a fascinating journey into the world of place value. But first, I have a fun challenge for you!

The Mystery Box

Imagine there is a mysterious box sitting in front of me. Inside this box, there are lots of colourful marbles—each with a different number written on it. Your task is to help me decode the secret message hidden in these numbers.

The Challenge

• I will pull out a marble from the box, and it will have a number on it (for example, 452).
• Your job is to tell me the value of each digit in the number and how many hundreds, tens, and units are in it.
• After that, we will work together to create a giant place value chart on the board!

Activity Preparation

1. Group Work: You will get into small groups.
2. Materials Needed: Each group will receive a set of marbles with different numbers on them.
3. Guiding Questions:
   • What does the digit 4 represent in 452?
   • How do we write this number using words and in expanded form?
   • How can we arrange the digits to form the largest and smallest numbers possible?

Conclusion

Let's see how many secret messages we can decode today and discover the magic of place value together! Who's ready to get started?
