Welcome to Fun Math with Fruits!

Hello everyone! Today, we’re going to learn how to add numbers in a fun way using fruits. Let’s get started!

Counting Apples

Look at the apples in the picture. Let’s count them one by one: one, two, three, four, five, six, seven, eight. There are eight apples!

We can add these apples in different ways. First, let’s count the apples in rows. The top row has four apples, and the bottom row also has four apples. So, we can say four plus four equals eight!

Now, let’s count the apples in columns. Each column has two apples. So, we have two plus two plus two plus two. Let’s add them: two plus two equals four, and another two plus two equals four. Finally, four plus four equals eight!

Counting Pears

Now, let’s look at the pears. Count them with me: one, two, three, four, five, six. There are six pears!

We can add these pears by counting the rows. The top row has three pears, and the bottom row has three pears too. So, three plus three equals six!

Let’s try counting in columns. Each column has two pears. So, we have two plus two plus two. Adding them gives us: two plus two equals four, and four plus two equals six!

Counting Tomatoes

Next, let’s count the tomatoes: one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve. There are twelve tomatoes!

We can add them by rows. Each row has three tomatoes. So, we have three plus three plus three plus three. Adding them gives us: three plus three equals six, and another three plus three equals six. Finally, six plus six equals twelve!

Now, let’s count the columns. Each column has four tomatoes. So, we have four plus four plus four. Adding them gives us: four plus four equals eight, and eight plus four equals twelve!

Counting Oranges

Finally, let’s count the oranges: one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen. There are sixteen oranges!

We can add them by rows. Each row has four oranges. So, we have four plus four plus four plus four. Adding them gives us: four plus four equals eight, and another four plus four equals eight. Finally, eight plus eight equals sixteen!

Let’s check the columns. Each column has four oranges. So, we have four plus four plus four plus four, which also equals sixteen!

  • What is your favorite fruit to count, and why do you like it? Can you think of a way to add them up in a fun way?
  • Have you ever helped someone count things at home or in the garden? What did you count, and how did you do it?
  • Can you think of other things around you that you can count and add together, just like we did with the fruits? How would you group them to make counting easier?
  1. Fruit Addition Hunt: Go on a fruit hunt in your kitchen or at the grocery store with a parent or guardian. Find different types of fruits and count them. Try to group them in different ways, just like we did with the apples and pears. Can you find a way to make groups that add up to ten? Share your findings with your family!

  2. Fruit Art: Draw a picture of a fruit basket. Fill it with different fruits and write down how many of each fruit you have drawn. Try to add them up in different ways, just like we did with the tomatoes and oranges. How many fruits do you have in total? Show your artwork to a friend and explain how you counted the fruits.

  3. Story Time with Numbers: Create a short story about a day at the fruit market. Include different fruits and how many of each you see. Use addition to describe how the fruits are arranged in rows or columns. For example, “I saw two rows of apples, each with three apples. How many apples did I see in total?” Share your story with your class or family and see if they can solve your fruit math problems!

There are many ways to represent the same number using addition. Today, we’re going to see how we can use repeated addition to find the total number of fruits shown in a picture. This will make adding a lot easier for us because we’ll just be adding the same number over and over again. We’ll start to see a pattern.

Here we have a group of apples. Let’s count them carefully one at a time to make sure we know how many there are: one, two, three, four, five, six, seven, eight. There are eight apples.

This problem can be easily represented in two different addition problems. First, we can count the top row across: one, two, three, four. That’s four. Then the bottom row: five, six, seven, eight. That’s another four. Both the top and the bottom rows have four numbers. This problem could be represented by four plus four, and we know that four plus four equals eight.

There’s another way to make eight easily from this picture. Let’s count how many in each column up and down: one, two. That’s two in the first column. Let’s count the rest: three, four. That’s another two. Five, six. Another two. Seven, eight. And another two.

We already know the answer is eight because we counted up to eight, but let’s just check anyway. First, let’s add the first twos: two plus two equals four. That’s an easy problem. Now the other twos: two plus two equals four again. Now we have two fours. We can add four plus four to get the total. Hopefully, you know what four plus four equals, but if not, maybe you can remember from my other example we did before: four plus four equals eight.

Let’s move on to the worksheet now.

I’ll read the directions first: Look at the trays with fruit and vegetables. Okay, I see them. How can you describe the number of fruit and vegetables on each tray? Check the boxes next to the correct addition sentences.

Let’s try the strategy we used before. First, let’s count the pairs: one, two, three, four, five, six. There are six pairs. I’m just going to write that down as a reminder.

Let’s see what easy addition sentences we can find to make six from this picture of pairs. First, let’s count the top row across: one, two, three. There are three pairs. Now let’s count the bottom row across: one, two, three. There are also three pairs on the bottom. So we can add three plus three, and we would get a total of six, which is the correct number of pairs. Three plus three is a good representation of this picture and the number six. Let’s put a check in the three plus three box.

Let’s count another way, up and down in the columns. We have one, two. Two in the first column. Three, four. That’s another two in this column. Five, six. The last two in the last column. So as you can see, we have three twos. We can add two plus two plus two.

We can add the first twos together: two plus two equals four. Then we’re left with four plus two, and four plus two gives us six. So we know that two plus two plus two equals six. This is a good representation of this picture and the number six. Let’s put a check in the two plus two plus two box.

Let’s check the sums or answers of the other equations shown. If they don’t equal six, we don’t need to go any further; they are not a good representation of this picture or the number six.

Three plus two equals five, so that is incorrect. And one plus one plus one equals three, and that’s not correct either.

Now we can check out our next problem. In this one, there are tomatoes. Let’s count them: one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve. There are twelve tomatoes.

Now let’s count each row across again to find an easy addition sentence: one, two, three. There are three tomatoes in the top row. One, two, three. There’s another three tomatoes in this row. One, two, three. That’s another three tomatoes. And one, two, three. That’s three more tomatoes in the last row. So as you can see, there are four groups of three.

Let’s add the first two threes together: three plus three equals six. Now we can add the second two threes together, and that equals six as well. So in the end, we can add six plus six, and six plus six equals twelve. So we could say that three plus three plus three plus three equals twelve and is a good representation of this picture of the tomatoes and the number twelve. Let’s check that box.

Now we can check the other easy way to represent twelve in this picture. We counted the rows across, so now let’s count the columns up and down. In the first column, we have one, two, three, four tomatoes. Let’s write four to keep track. One, two, three, four tomatoes in this one. And one, two, three, four tomatoes in this one too. Nice even columns! It looks like we have ourselves four threes.

Let’s add them together. We’ll start with the first two: four plus four equals eight. Now you can add the other four that you have left with the eight, and four plus eight is twelve. So you could see that four plus four plus four is also a good representation of twelve in this picture. Let’s put a check in that box too.

Now we can check the other ones quickly just by seeing if they add to twelve. Let’s see: four plus four plus three plus three. Well, I know that four plus four equals eight, and three plus three equals six. So I have to add eight plus six to find out if it’s a good representation of twelve.

Six plus eight equals fourteen, so that one is no good. And finally, we have four plus three, and well, that just equals seven, so that does not represent this picture or the number twelve.

Let’s look at the last problem. We have some oranges. Let’s count the oranges: one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen. There are sixteen oranges.

Now let’s count each row across again to find an easy addition sentence: one, two, three, four. There are four oranges in the top row. One, two, three, four. There are four oranges in this row. One, two, three, four. There’s another four oranges in this row. And one, two, three, four. There’s another four oranges in the last row. So there are four groups of four in this picture.

Let’s add the first two fours together. We know that four plus four equals eight. Now let’s add the second fours together: four plus four equals eight again. So we’re left with eight plus eight. We can add eight plus eight, and eight plus eight equals sixteen.

So we could say that four plus four plus four plus four equals sixteen and is a good representation of this picture and the number sixteen. Let’s check the four plus four plus four plus four box.

We can quickly check to see if the other equations are a good representation of sixteen in this picture by simply adding them together to see if they equal sixteen.

We’ll start with three plus three, and well, that just equals six, so that’s wrong. And four plus four equals eight, so that’s wrong too. Let’s try two plus four plus two plus four.

We can use the same strategy as before by adding the first two numbers together: two plus four, and that equals six. Now we can add the other two numbers: two plus four again, and that equals six. So we’re left with six plus six to see if it equals sixteen. But it does not; it equals twelve.

So two plus four plus two plus four is not a good representation of this picture or of the number sixteen.
