Multiply Magic! Script

Introduction & Hook (5 minutes)

"Good morning, everyone! Today, we're going to unlock some math magic that will help us count things super fast. Have you ever had to count a lot of things that were in equal groups? Like, if you had a bunch of candy bags, and each bag had the same amount of candy? How would you count all the candy quickly?"

(Listen to student responses. Guide them towards the idea of adding the same number over and over.)

"That's a great start! Sometimes, adding the same number again and again can take a little while. What if there was an even faster way? Today, we're going to learn about something called multiplication, and it's like a superpower for repeated addition!"

Understanding Repeated Addition (10 minutes)

"Let's look at our Multiply Magic! Slides. Imagine you have 3 plates, and each plate has 4 cookies. If we wanted to find the total number of cookies, we could add 4 + 4 + 4. What does that equal?"

(Wait for responses, guide them to 12.)

"Exactly! 4 + 4 + 4 = 12. Now, multiplication is a shortcut for this. Instead of saying '4 plus 4 plus 4,' we can say '3 groups of 4.' And in math, 'groups of' means we can multiply! So, 3 groups of 4 cookies is written as 3 x 4. And guess what? 3 x 4 also equals 12!"

(Show another example on the board or refer to the slides.)

"Let's try one together. Look at this example on the Multiply Magic! Slides: You have 5 friends, and each friend has 2 balloons. How many balloons in total? First, think about it as repeated addition. What would that look like?"

(Give students a moment to think and share: 2 + 2 + 2 + 2 + 2.)

"Great! And what does that add up to?"

(Guide them to 10.)

"So, if we use our multiplication magic, how would we write '5 groups of 2'?"

(Wait for '5 x 2'.)

"Perfect! And 5 x 2 equals 10, just like our repeated addition! Do you see how multiplication is a speedy way to solve these kinds of problems?"

Worksheet Practice (10 minutes)

"You're doing fantastic! Now, it's your turn to practice this multiply magic. I'm going to hand out the Multiply Magic! Worksheet. On this worksheet, you'll see problems where you need to change repeated addition into multiplication, and some where you'll solve multiplication problems by thinking of them as repeated addition.

"Remember, if you get stuck, think 'groups of.' If it helps, you can even draw little groups or use your fingers to count. I'll be walking around to help anyone who needs it. When you're done, we'll review some of the answers together. Any questions before we start?"

(Distribute worksheets. Circulate and provide individual support. After about 8 minutes, bring the class back together.)

"Alright, let's look at a couple of these problems together. Can someone share how they solved question number 1? How about question number 3?"

(Use the Multiply Magic! Answer Key to guide the discussion and ensure correct understanding.)

Wrap-up & Cool Down (5 minutes)

"Excellent work today, mathematicians! We learned that multiplication is a super-fast way to do repeated addition. It helps us count groups much quicker.

"Before we finish, can everyone tell me one new thing they learned about multiplication today, or one question they still have? You can tell me quietly as you pack up, or if we have time, share with a partner. We can also do a quick Cool Down if there's a moment. Great job, everyone!"

Multiply Magic! Answer Key

Part 1: Repeated Addition to Multiplication

1. 3 + 3 + 3 + 3 = 12
   Multiplication: 4 x 3 = 12
   Thought Process: The number 3 is added 4 times, so it's 4 groups of 3.

2. 5 + 5 + 5 = 15
   Multiplication: 3 x 5 = 15
   Thought Process: The number 5 is added 3 times, so it's 3 groups of 5.

3. 2 + 2 + 2 + 2 + 2 + 2 = 12
   Multiplication: 6 x 2 = 12
   Thought Process: The number 2 is added 6 times, so it's 6 groups of 2.

4. 10 + 10 = 20
   Multiplication: 2 x 10 = 20
   Thought Process: The number 10 is added 2 times, so it's 2 groups of 10.

5. 4 + 4 + 4 + 4 + 4 = 20
   Multiplication: 5 x 4 = 20
   Thought Process: The number 4 is added 5 times, so it's 5 groups of 4.

Part 2: Multiplication as Repeated Addition

6. 4 x 3 = 12
   Repeated Addition: 3 + 3 + 3 + 3 = 12
   Thought Process: 4 x 3 means 4 groups of 3, so add 3 four times.

7. 2 x 5 = 10
   Repeated Addition: 5 + 5 = 10
   Thought Process: 2 x 5 means 2 groups of 5, so add 5 two times.

8. 3 x 6 = 18
   Repeated Addition: 6 + 6 + 6 = 18
   Thought Process: 3 x 6 means 3 groups of 6, so add 6 three times.

9. 5 x 2 = 10
   Repeated Addition: 2 + 2 + 2 + 2 + 2 = 10
   Thought Process: 5 x 2 means 5 groups of 2, so add 2 five times.

10. 1 x 7 = 7
    Repeated Addition: 7 = 7
    Thought Process: 1 x 7 means 1 group of 7, so it's just 7.

Challenge!

11. You have 4 bags, and each bag has 3 stickers. How many stickers do you have in total? Show your work using both repeated addition AND multiplication.

    Repeated Addition: 3 + 3 + 3 + 3 = 12

    Multiplication: 4 x 3 = 12

    Answer: You have a total of 12 stickers.

    Thought Process: Identify the number of groups (4 bags) and the number in each group (3 stickers). Then, express this as repeated addition and multiplication to find the total.
