“Good morning! Today, we are going to learn about addition strategies. Do you remember what addition means? That's right! Addition is when we put numbers together to find a total.
Now, there are different ways to add numbers, and today we will explore some of these strategies. Can anyone tell me if they’ve heard about counting on, using doubles, or making ten? Great!
Let's start with counting on. If I have 5 and I want to add 3 more, I can start at 5 and count up: 6, 7, 8. So, 5 plus 3 equals 8.
Now, what about using doubles? If I want to add 4 and 4, I think of it as 4 plus 4, which I already know is 8.
And making ten? If I want to add 8 and 5, I can make 10 by taking 2 from the 5 to make 10. That leaves me with 3 because 5 minus 2 is 3. So, 8 plus 5 equals 13!
Today, we’ll practice these strategies together. Are you ready to get started?”
“Let’s work on some addition problems together. I have some manipulatives here—these counting blocks.
I’ll start with the problem: 4 plus 3. Let’s use our manipulatives. Can you show me 4 blocks? Good! Now, can you add 3 more blocks?
Count all the blocks together. How many do we have? Yes, that's right, 7!
Now let's try another one. What if I have 6 plus 2? Get your blocks ready. What’s 6? Perfect! And now add 2 more. Count them aloud. Wonderful! You got 8!
Let’s do one more using the strategy of making ten. If I have 9 plus 5, do you think we can make ten with that? Yes! Take 1 from the 5 and add it to 9. How many do we have now? That’s right, 10! How many do we have left from the 5? Yes, 4! So, 9 plus 5 equals 14. Great job!”
“Now it's your turn to practice on your own with this worksheet I have for you. It has some addition problems for you to solve.
Remember, you can use any of the strategies we talked about today: counting on, using doubles, or making ten.
Take your time, and if you have any questions, don’t hesitate to ask me. I’ll be walking around to help.
Ready? Go ahead and start answering the problems!”
“Alright! Time is up. Let’s go over the answers together. I’ll read each problem, and you can tell me what you got.
For the first problem, what was 3 plus 4? That’s right, it’s 7!
How about 6 plus 3? Yes, it’s 9!
And what about the one that was 5 plus 7? Correct, it's 12!
Now, while we go through these answers, can you tell me what strategy you used to solve any of them? Good! You can use counting on or even doubles.
Remember, there’s no one right way to add, but using these strategies can help you find the answers more quickly!”
“Before we finish today, I want to explain your homework. You will be working on a worksheet that has more addition problems for you to practice.
You should use the strategies we learned in class today: counting on, using doubles, or making ten.
Make sure to show your work so that we can go over it in our next lesson. Do you have any questions about the homework? Great!
I'm really proud of the effort you put into today’s lesson. Keep practicing, and I’ll see you next time!”
Can you think of a real-life situation where you might need to use addition? Describe it to the class.
If you had to explain the strategy of counting on to a friend who missed the lesson, how would you do it?
What is your favorite strategy for solving addition problems, and why do you like it the most?
If you had 7 blocks and you wanted to add 5, how could you use the "making ten" strategy to find the answer?
Can anyone come up with a different way to represent the problem 4 plus 6 using objects or drawings? Show us your example!
