Introduction

Imagine you're an astronaut on a mission to explore a distant planet. As you prepare for landing, you need to calculate how many supplies you'll need. But here's the twist—everything is measured in units of 10, 100, and 1000! Today, we're going to become math astronauts and learn how to multiply and divide by 10, 100, and 1000.

A Mysterious Mission

The Scenario

You've just received a message from the Space Command Centre. They’ve sent you a list of supplies you’ll need for your expedition. Below is the list:

Your mission is to figure out how much of each supply you'll need to take depending on different scenarios of crew sizes. We’ll look at what happens when you multiply and divide these amounts by 10, 100, and 1000.

The Challenge

Question 1: If each astronaut needs 5 litres of water, how much water will you need for 10 astronauts?
Question 2: If you switch to 100 astronauts, how much will you need?
Question 3: Let's say you only have 1 astronaut—how much water would you need in litres? This time, divide the amount needed for the 10 astronauts by 10.

Hands-On Activity

To gather your supplies, let's do some calculations together!

  1. Multiply: Write down what you think the new amounts of supplies will be if we need to multiply by 10, 100, and 1000.

    • For example:
      • Water for 10 astronauts: ( 5 \times 10 = ? )
      • Food for 10 astronauts: ( 25 \times 10 = ? )
      • Fuel for 10 astronauts: ( 700 \times 10 = ? )

  2. Divide: Now let's divide the information you calculated back down to understand how much would be needed for just 1 astronaut.

    • For instance:
      • Water for 1 astronaut: What's ( 50 \div 10 )?
      • Food for 1 astronaut: What's ( 250 \div 100 )?
      • Fuel for 1 astronaut: What's ( 7000 \div 1000 )?

Conclusion

By the end of today’s lesson, you will not only understand how to multiply and divide by 10, 100, and 1000, but you’ll also be ready to stock your space journey with the right amounts of supplies! Don't forget: every good astronaut knows that accurate calculations are the key to a successful mission.

So, let’s ignite our engines and take off into the world of maths—are you ready? 🚀
