The Great Snack Showdown

Attention Grabber:

Teacher enters the classroom with two large bags of snacks: one filled with chips and the other with pretzels.

"Good morning, everyone! Today, we’re about to embark on a delicious mathematical adventure that involves a friendly showdown between snacks! But first, let’s think about something important: If I tell you that I have 30 bags of chips and 15 bags of pretzels, how many times more chips do I have compared to pretzels? And more importantly, does it really matter?"

Making It Relatable

1. Discussion Prompt:
   • "Imagine you were hosting a party and needed to prepare an ideal snack mixture for your friends. What ratios would you use to determine how many chips and pretzels to buy? Would your choice change if you were catering to a group that prefers one snack over the other?"
