Exciting Math Adventure: The Treasure Hunt!

Objective

Today, we will embark on an exciting treasure hunt that will involve solving 3-digit addition problems with regrouping. Are you ready to uncover the hidden treasure?

Introduction

A Mysterious Map

Imagine you are a brave explorer, and you've just found an ancient treasure map! This map has clues that will help us find the treasure, but there’s a twist—it’s missing some important numbers! To fill in the map, we need to complete some 3-digit addition problems. Don’t worry; we will work together as a team!

Setting the Scene

The Treasure Map Clue:

The first clue on our treasure map states:

"In the enchanted forest, there are 125 bright blue butterflies and 237 glowing fireflies! How many colorful creatures are there altogether?"

Task:

We need to solve this addition problem to uncover the total number of creatures in the forest!

Interactive Group Activity:

  1. Gather Around: Form groups of 3 or 4. You will each have an addition problem to solve.

  2. Treasure Tools: Each group will receive:

    • A set of counters (small objects) to represent each digit.
    • Whiteboard markers and mini whiteboards to write your work.

  3. Let’s Solve Together: Follow these steps:

    • Align the numbers vertically, making sure that the hundreds, tens, and ones are in their correct columns.
    • Add the ones column first. If the total is 10 or more, regroup!
    • Next, add the tens column and remember to include any regrouped tens.
    • Lastly, add the hundreds column.

The Big Reveal

Once you and your team have completed the addition, raise your hands and share your answers!
