| Full lesson | Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle} |

"Good morning, class! Today, we will continue our exploration of fractions, an important concept in mathematics. Before we dive into our new lesson, let’s do a quick review.
Who can remind me what a fraction consists of? Yes, that's right! A fraction has two parts: the numerator and the denominator. The numerator tells us how many parts we have, while the denominator tells us how many equal parts the whole is divided into.
Let’s think of an example. If we have the fraction 3/4, what does the 3 represent? Great! It represents 3 parts out of 4 equal parts of a whole.
Now, can anyone give me an example of their own? Excellent! Those are some good examples. We use fractions in our everyday lives, from cooking to sharing. Today, we are going to learn how to multiply fractions."
"Now that we’ve revisited what fractions are, let’s talk about how we multiply them. When we multiply two fractions together, we multiply the numerators and then multiply the denominators.
For example, if we want to multiply 1/2 by 3/4, we take the numerator 1 and multiply it by the numerator 3. What do we get? Yes, we get 3!
Next, we take the denominator 2 and multiply it by the denominator 4. What is that? Correct, it’s 8!
So, when we multiply 1/2 by 3/4, we get 3/8. It’s as simple as that! Let’s try another example together on the board before we move on.
Can someone suggest another pair of fractions for me to multiply? Great choice! Let’s say we multiply 2/3 by 1/2. What’s our numerator going to be? Yes, 2 times 1 is 2. And what about our denominator? Yes! 3 times 2 is 6. So, we get 2/6! Does anyone know if we can simplify that? Perfect! It simplifies to 1/3.
Now everyone, are you ready to practice this on your own? Let’s move on!"
"I'm going to hand out printable fraction cards to each of you. These cards contain multiplication problems that we just learned about.
Before you start, I want you to read through your cards and see if you can understand each task. You’ll have a chance to multiply the fractions on your own, showing what you’ve just learned.
As I pass these out, please make sure to write your name at the top of your card.
Are we ready? Here you go!"
"Now it’s time for you to work independently on the problems from your cards. Take your time and do your best.
I’ll be walking around to see how you’re doing and to help if someone gets stuck. Remember the steps we discussed: multiply the numerators, then multiply the denominators.
If you finish early, feel free to check your answers against the class or even help a friend. Let’s get started!"
"Okay, everyone, time's up! I’m going to collect your fraction cards now.
I may also check a few of them randomly to see how you're doing. If I call your name, please pass up your card. Don't worry about presenting; I just want to gauge your understanding of multiplying fractions based on your work.
Thank you for your effort today!"
"Great job today, class! Let’s quickly review what we learned about multiplying fractions. Who can tell me the steps to multiply fractions?
That's right! We multiply the numerators and then multiply the denominators, and lastly simplify if we can.
Do you have any questions about what we learned today?
Fantastic! For homework, I will give you a worksheet with more fraction multiplication problems to complete. Please make sure you bring it back completed next class.
Thank you all for your hard work today; I’m excited to see how you do on the homework!"
