Exciting Beginning to Our Maths Lesson: Adding with Partitioning!

🌟 Introduction: A Math Adventure Awaits!

Good morning, Year 5! Today, we’re going to embark on an exciting adventure into the world of Adding with Partitioning. Are you ready to explore this new method that will make addition even more fun and easier?

📦 The Mystery Box Challenge

Let's Unveil the Mystery!

To kick off our lesson, we’ll play the Mystery Box Challenge! I have brought a special box filled with a variety of items. Inside, you'll find 3 different types of blocks in different colours. Each block type represents a different value:

Red Block = 10
Blue Block = 5
Green Block = 1

How It Works

Gather Around: Everyone will gather in small groups around the Mystery Box.
Choose Your Blocks: Each group will take turns to reach into the box and pick out a total of 25 blocks. You can choose any combination of red, blue, and green blocks!
Count Your Total: After selecting your blocks, your group will work together to talk about how many of each colour you have.
Partitioning Time: Once you’ve counted, I want you to write out your total in two ways:
- Using partitioning to show how you arrived at 25.
- As a regular addition sum (e.g., 10 + 10 + 5 + 1 = 26).

Share Your Discoveries

After you’ve done the calculating, each group will share:

What combinations of blocks you used.
How you partitioned your numbers.

🎉 Why This Matters!

Understanding how to add using partitioning makes adding large numbers much easier, and it helps us see the relationships between different numbers. By using the blocks, we’re not only having fun, but we’re also visualising how addition works!

So, are you ready to dive into the Mystery Box Challenge? Let’s unleash our inner mathematicians and start our journey of adding with partitioning! 🧮✨
