Creative Lesson Introduction: Multiplying Two-Digit by Two-Digit Numbers
Introduction to the Challenge
Welcome, Future Mathematicians!
Today, we are diving into the exciting world of multiplying two-digit numbers! To kick off our lesson, let’s imagine that we are all entrepreneurs in a vibrant marketplace. Each of you is the proud owner of your own lemonade stand. Now, we have a fun challenge ahead of us!
The Lemonade Stand Challenge
Imagine that you can customize your lemonade stand by offering various flavors. Here’s the challenge:
- You can create 10 different flavors of lemonade.
- Each flavor you create has its own special recipe for the number of lemons and sugar needed.
However, to make a gigantic batch for the summer festival, you need to calculate how many total ingredients you’ll need if each recipe is for 2-digit flavors.
The Festival
Imagine that each recipe uses a different amount of ingredients: one recipe uses 12 lemons and 15 cups of sugar, while another might use 23 lemons and 32 cups of sugar. If we want to make 20 servings of each flavor for the festival, we must multiply the ingredients.
Your Task
- Flavor Creation: Think of two-digit numbers that represent the ingredients needed for your two lemonade flavors. Write them down!
- Multiplication Magic: We’ll multiply these numbers together to find out how many total ingredients you need for both lemonade flavors when multiplied by the number of servings.

Lesson Objectives
- Understand how to multiply two-digit numbers.
- Apply multiplication skills in real-world scenarios.
- Enhance problem-solving and critical thinking through a fun, thematic approach.
Warm-up Exercise
Before we dive into the main lesson, let’s do a quick warm-up! In pairs, come up with your own two-digit ingredient amounts and share them with your class. We’ll pick a few pairs to multiply together and share our results.
Example Warm-up
- Flavor 1 Ingredients: 14 lemons and 18 cups of sugar
- Flavor 2 Ingredients: 21 lemons and 25 cups of sugar
Let's multiply these ingredients on the board and see how many we need for our lemonade festival!
By presenting the lesson in this thematic, relatable context, students can connect mathematical concepts to real-life situations, making learning more engaging and enjoyable!
