A Fun Introduction to Multiplying 2-Digit Numbers with Decimals

Objective

Today, we are going to dive into the exciting world of multiplying 2-digit numbers with decimals! We'll learn how to do it step-by-step while having some fun along the way.

Warm-Up Activity: The Grocery Store Game

What You’ll Need:

Instructions:

  1. Set Up Your Grocery Store: Place the price tags on various items you have created, assigning them different values that include decimals. For example:

    • Apples: $4.20
    • Bananas: $1.75
    • Cookies: $2.50
    • Milk: $3.00
  2. Choose Your Items: Each student picks two items they want to 'buy' from your grocery store. Encourage students to think about how much it costs in total.

  3. Calculate the Total Cost:

    • Ask students to calculate how much it would cost if they wanted to buy 3 of each item. For instance, if a student picks cookies ($2.50) and milk ($3.00), they will find:
      • Cookies: 3 x $2.50 = $7.50
      • Milk: 3 x $3.00 = $9.00
    • Together, we will add these totals to find the total cost of their shopping.
  4. Discuss the Process:

    • Explain what they just did! They multiplied each price (a 2-digit number with a decimal) by 3. This is the first step we are going to work on today!

Transition to Lesson

Now that we've had a chance to practice our math in a fun, real-world scenario, let's grab our notebooks and dig deeper into the steps of multiplying 2-digit numbers with decimals. We will learn how to align numbers and properly place the decimal point in our answers!


By using this interactive and playful approach, students can relate their mathematical skills to everyday activities, making the learning process both engaging and practical.
