| 1 | Introduction | 5 | Briefly introduce the topic of adding integers. Explain the importance of understanding positive and negative numbers. Use examples on the whiteboard. |
| 2 | Checking Homework | 5 | Review the homework assignments without student presentations. Quickly go over answers and clarify any misconceptions. Gather feedback on common mistakes. |
| 3 | Interactive Card Activity | 10 | Distribute printable cards to each student. Explain that they will fill in the cards with problems as they work through examples on the board. Encourage collaboration and discussion among peers. |
| 4 | Guided Practice | 5 | Solve integer addition problems as a class. Call on students to contribute their answers and reasoning. Ensure understanding through guided questioning. |
| 5 | Independent Practice | 5 | Hand out worksheets with integer addition problems for individual practice. Monitor students as they work and provide support where needed. |
| 6 | Collecting Cards | 3 | Circulate the classroom to collect or randomly check the cards students filled out. Ensure they have attempted the problems and understood the concepts. |
| 7 | Assigning Homework | 2 | Assign homework related to adding integers, instructing students to attempt a set number of problems to reinforce today's lesson. |
Reiterate the importance of adding integers in daily life and other subjects. Summarize key points of the lesson, ensuring that students are clear on the assignment due next class.
After the lesson, the teacher should reflect on what worked well and what could be improved upon for future lessons, considering student engagement and understanding of the material.
"Good morning, everyone! Today, we are going to dive into the topic of adding integers. This is an essential skill not just in mathematics, but also in real life—think about temperatures, bank accounts, or even video game scores! Understanding how to add positive and negative numbers will help us solve many problems.
Look at the whiteboard. Let’s start with a simple example: What’s 5 + (-3)? Who can tell me the answer? That’s right! It’s 2. Great job! Now, let’s explore more examples and see how this works in various situations."
"Next, let’s take a few minutes to review the homework you had from the last lesson. I’m just going to go over the answers quickly, and please feel free to raise your hand if you have any questions.
Alright, for the first problem, the answer was 7. How about the second one? Yes, that’s -1. I noticed a few common mistakes, especially with adding negative signs, so let’s keep those in mind as we move forward. If you struggled with any particular problem, jot it down, and we can discuss it later!"
"Now it’s time for some collaboration! I’m going to hand out these printable cards to each of you. I’d like you to work with your neighbors to fill in the cards with integer addition problems.
As you fill in the problems, feel free to discuss them together. Remember, this is a great opportunity to learn from one another, so don’t hesitate to share your thoughts. I’ll give you about 10 minutes for this activity—let's get started!"
"Alright class, let’s come back together. Now we’re going to do some guided practice as a group. I’ll write a few problems on the board, and I want you all to help me solve them.
Here’s the first one: -4 + 9. Who wants to share what they think the answer is and how they calculated that? Yes, exactly! It’s 5 because we are moving from -4 to 9 on the number line. That’s great reasoning! Let’s do another one—who can help me with 3 + (-8)?"
"Wonderful! Now, it’s time for you to do some independent work. I’m handing out worksheets with integer addition problems for you to practice on your own.
Take your time, and make sure to show your work. If you have questions or need assistance, please don’t hesitate to raise your hand. I’ll be walking around to help you. You’ll have 5 minutes to complete as many problems as you can—let’s go!"
"Okay, time’s up! I hope you all felt confident with those problems. Now I’m going to come around and collect or check the cards you filled out during the activity earlier.
It’s important to ensure you attempted the problems on your cards. If you have any questions about those problems while I’m checking, feel free to ask me. Let’s make sure we're on the same page!"
"Great job today, everyone! For your homework, I’d like you to complete a set of problems related to adding integers. Please try to do at least 10 problems that involve both positive and negative integers.
This will reinforce what we learned today, and I’m really expecting to see how you apply what we discussed. Remember to bring any questions you have to our next class!"
"Before we wrap up, let’s quickly summarize what we learned today. Adding integers is not only an important mathematical skill but it’s also applicable in everyday scenarios. It’s essential to understand how to work with both positive and negative numbers.
Remember, you all did a fantastic job engaging today, and I can’t wait to see your homework. Have a great day, and remember to think about how integers appear in your everyday life!"
