Introduction: The Mystery of the Missing Numbers

Opening Scenario

Attention, young mathematicians! 🧑‍🏫✨ Today, we have an exciting mystery to solve!

Imagine that you are detectives in a magical land called Numberville. In Numberville, a delightful festival is about to take place, but oh no! Some of the festival tickets have gone missing! 🎟️

Your mission, should you choose to accept it, is to uncover how many tickets are left by solving some tricky 3-digit subtraction problems.

Engagement Activity

To get started, let’s take a look at a special box. Inside it, we have 432 festival tickets. But oh dear, the mischievous Number Goblin has taken away some tickets! 🧝‍♂️

Can you help us figure out how many tickets are left after the mischievous goblin took some?

Problem to Solve

Let’s say the goblin took 158 tickets. How many tickets are remaining for the festival? 🤔

  1. Write it down: 432 - 158 = ?
  2. Break it down: We will subtract 3 digits step by step – hundreds, tens, and ones.
  3. Make it fun: Let’s think of it as a fun treasure hunt! We’re going to find out what treasure (or number) we are left with!

Transition

Once you have your answer, raise your hand and share what you found! Let’s gather as a team and make sure our Numberville festival can go on smoothly. Who knows? Maybe you’ll all win a special reward for being such skilled detectives!

Let’s dive into the world of 3-digit subtraction together! Are you ready? 🚀
