"Good morning, class! Today, we are going to learn about double digit multiplication. Can anyone tell me why multiplication is important in our daily lives? That's right! We use it when we calculate prices while shopping, combine groups of items, or even when we are working with measurements in cooking. Mastering this skill can make math much easier! Now let's dive into our lesson."
"Now I'm going to show you how to multiply double-digit numbers using the standard algorithm. Let’s work through an example together. I'll write the problem '23 multiplied by 15' on the whiteboard.
First, we start with the ones place. We take 5 (which is in the ones place of 15) and multiply it by 3 (which is in the ones place of 23). What do we get? Yes, 15! We write down the 5 and carry over 1. Next, we multiply 5 by 2, which gives us 10, and we add the 1 we carried over, giving us 11. So far we have:
1
23
x15
-----
115 (This is from the first step)Now, we move to the tens place. We take the 1 (which is in the tens place of 15) and multiply it by 3. What do we get? Exactly, 3! Now we need to remember that this 3 is in the tens place, so we write it down one place to the left.
Next, we take 1 and multiply it by 2. What do we get? Correct, 2! So now let’s add everything up to finish the problem. What is 115 plus 230? Yes, it’s 345! So, 23 multiplied by 15 is 345. Great job!"
"Now it’s your turn to practice, but we are going to work in small groups. I will divide you into 4 groups. Each group will receive a set of sample double digit multiplication problems.
Once I hand these out, work together to solve them. Remember to use the standard algorithm we just went through. I will walk around to each group to check in and help you if you have any questions. If you feel stuck, don’t hesitate to ask your teammates or me for help!
Let’s take 10 minutes for this activity. Ready? Go!"
"Fantastic job, everyone! Now, I’m going to give you a worksheet that has double digit multiplication problems for you to solve on your own. Remember how we practiced together; use the same method.
You will have 5 minutes to complete as many problems as you can. Once you finish, make sure to double-check your work. Okay, I’m setting the timer now. Good luck!"
"Alright, time’s up! Please put your worksheets aside. For your homework, I’d like you to complete another set of double digit multiplication problems that I will describe. Make sure to practice at least five problems from the worksheet I will provide. I know you can do it. I will collect your completed worksheets at the end of class today, so make sure to stay focused!"
"Thank you for your hard work today! Let’s quickly recap what we learned. We covered the standard algorithm for double digit multiplication and worked through several examples, both together and in groups.
Remember, practice is key to mastering multiplication. Please check your homework against the classroom examples to see where you might improve. Can't wait to see how you all did in our next class! Enjoy the rest of your day!"
Multiply the following double-digit numbers using the standard algorithm:
Explain the steps you took to solve one of the problems above using the standard algorithm. What did you find challenging?
Create a double-digit multiplication problem of your own and solve it, showing all your work clearly.
Choose one of the problems you solved in questions 1 or 3 and check your work. What is the correct answer? Did you find any errors? If so, where?
Why do you think mastering double-digit multiplication is important? Provide at least two real-life examples where you might use this skill.
Challenge Question: If you multiply a two-digit number by another two-digit number, what is the maximum possible result? Explain how you arrived at your answer.
Reflect on your homework. How confident do you feel about double-digit multiplication now compared to when we started the lesson? What will you do to continue improving?
