| 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} |

Addition and Subtraction
Year 2
Mathematics
30 students
| Step Number | Step Title | Length | Details |
|---|---|---|---|
| 1 | Introduction | 5 min | Introduce the topic of addition and subtraction. Engage students with a question about their familiarity with these concepts. |
| 2 | Part-Part-Whole Diagrams | 10 min | Explain and model how to use part-part-whole diagrams. Provide examples related to addition and subtraction facts. Use visual aids. |
| 3 | Guided Practice | 10 min | Divide students into small groups. Use materials to create their own part-part-whole diagrams, demonstrating both addition and subtraction facts. |
| 4 | Introduction to Equivalence | 5 min | Introduce the concept of equivalence using balance scales. Provide examples, such as 7 + 8 = 6 + 9. Discuss with students. |
| 5 | Independent Practice | 10 min | Distribute worksheets that include creating and solving addition and subtraction number sentences. Encourage students to show their work. |
| 6 | Homework Assignment | 5 min | Briefly explain the homework assignment. It should focus on addition and subtraction problems that reinforce learning. Homework is to be checked but not presented. |
| 7 | Conclusion and Review | 5 min | Recap the day’s lessons. Ask students to reflect on what they learned about addition and subtraction. Gather feedback to inform future lessons. |
"Good morning, everyone! Today we are going to explore the exciting world of addition and subtraction! Can anyone raise their hand and tell me what addition means? Great! And what about subtraction? Yes, that's right! Addition is when we put things together, and subtraction is when we take things away. Let's all get ready to dive deeper into these important math concepts!"
"Now, let’s talk about something called part-part-whole diagrams. These diagrams help us understand how addition and subtraction are related. I will show you an example on the whiteboard.
Imagine we have 10 apples. If we put 6 apples in one basket and 4 in another, the part-part-whole diagram shows us the two parts: 6 and 4, and the whole, which is 10. Can you all see how these numbers connect?
Now, let's look at some examples together. What would the part-part-whole diagram look like for 5 + 3 = 8? Yes, the two parts are 5 and 3, and the whole is 8! Perfect!"
"Now it’s your turn! I want you to get into small groups of 4. Each group will create their own part-part-whole diagram using the materials I’m giving you. Use the counters to represent different addition and subtraction facts.
For instance, you might want to show that 7 and 2 make 9. Remember, each group should come up with at least two diagrams. I’ll walk around to help if you need any assistance. Let's get started!"
"Okay, everyone, time to introduce a new and exciting concept: equivalence! We are going to use some balance scales to understand this idea better.
When two things are equivalent, it means they are equal, even if they look different. For example, if I have 7 + 8 on one side of the scale, does anyone know what could balance it on the other side? Yes! You could have 6 + 9!
Can anyone else think of other number sentences that show equivalence? Perfect! It's amazing how many different ways we can show equality!"
"Now it’s time for some independent practice. I will hand out worksheets that have a variety of problems involving addition and subtraction. You’ll be creating and solving number sentences and should show your work in the space provided.
Take your time, and if you have any questions, feel free to raise your hand. Remember, this is your chance to demonstrate what you’ve learned today!"
"Great job, everyone! Before we wrap up, I want to explain today's homework assignment. You will receive a worksheet that contains practical addition and subtraction problems, as well as some questions about equivalent number sentences.
Make sure you complete it by our next class. Remember, I will be checking your homework for feedback, but there's no need to present it in front of the class. You've got this!"
“Alright, everyone, let's recap what we've learned today! Can anyone tell me the importance of addition and subtraction? Yes, they help us understand how to combine numbers and take them away.
And what did we learn about part-part-whole diagrams? Correct! They help us see the relationship between parts and the whole.
Lastly, can anyone remind me what equivalence means? Excellent! It’s about finding equality in different number sentences.
Thank you all for your hard work today! I’d love to hear your thoughts on what you found most interesting. Who would like to share?"
