Warm-Up Activity: The Market Challenge

Setting the Scene:

Imagine you are planning a big funfair at your school, and you have a budget to manage. There are two interesting stalls you want to set up: a Cotton Candy Stand and a Hot Dog Cart. Each stall requires a certain number of items to operate, and the costs of these items are given in two-digit numbers.

Engaging Questions:

1. Cotton Candy Stand: To run the stand, you will need 22 bags of sugar. Each bag costs $15.

   • How much will you spend on bags of sugar?

2. Hot Dog Cart: For the hot dog cart, you want to sell 35 hot dogs, and each hot dog is priced at $12.

   • How much will you spend on hot dogs?

Brain Teaser:

Before we dive into the math, consider this puzzle:
If setting up both stalls costs you a total of $X, what will $X be if you add the costs of both stands?

Group Discussion:

After students write down their calculations, form groups to discuss:

• What strategies did you use to calculate the total costs?
• Was there any trick you used to make it faster or easier?
• How do you think multiplying two-digit numbers could help in managing a real budget?

Transition to Lesson Content:

Now that you've brainstormed and calculated the costs, let's dive deeper into how we can multiply two-digit numbers efficiently! We will explore various methods, including the traditional algorithm, the distributive property, and even some mental math strategies.
