Unlocking the Mystery of Rates: A Memorable Beginning

Introduction to the Lesson

Welcome, Year 8 mathematicians! Today, we are diving into the fascinating world of rates. But before we get started, let's set the scene with a fun and engaging activity that will grab your attention and ignite your curiosity!

The Great Snack Rate Challenge

Objective: Understand the concept of rates through a hands-on activity.

Activity Setup

1. Materials Needed:

   • A selection of popular snacks (chips, chocolate bars, lollies) and drinks (soft drinks, bottled water).
   • Price tags for each item (real or fictional prices).
   • Paper and pens for calculations.

2. The Challenge: Tell the students they’re at a school canteen that’s having a special promotion on snacks and drinks. Each item has a different price, and students must calculate the rates (price per unit) for their favourite snacks and drinks.

Instructions

1. Form Groups: Divide the class into small groups of 3-4 students.
2. Select Snacks: In each group, students will select two or three different snacks or drinks from the provided selection.
3. Calculate Rates: Using the price tags, each group calculates the cost per serving (for example, how much it costs for one chip, one sip of drink, etc.), leading to discussions about finding the rate.
4. Share Findings: After 10 minutes, each group will present their calculations and discuss which item provides the best value based on their rates.

Discussion Points

• Why is it important to know the cost per unit?
• How can understanding rates help us make better purchasing decisions?
• Are some rates more valuable than others, and why?

Conclusion

As we wrap up this engaging challenge, we’ll transition to more structured examples of rates in everyday life, linking our discussion back to real-world applications. By the end of the lesson, you’ll be able to not only calculate rates with confidence but also recognise their significance in both shopping and other areas of your daily life!
