2. Let’s Start!
Ana went to her garden
and planted some carrots
and radish seedlings. She
watered and took care of
her seedlings. Soon, they
started to grow.

3. How many carrot seedlings does Ana have?
5 carrot seedlings
How many radish seedlings does Ana have?
5 radish seedlings

4. How many seedlings does Ana have
in her garden?
Putting together 5 carrot seedlings
and 5 radish seedlings, Ana has 10
seedlings in the garden.
5 and 5 makes 10

5. Addition sentence: 5+5=10
5
+5
10
Addends
Sum

6. We can also use a number line to
show addition.
Let’s use the number line to add 5
and 5.

7. On the number line, we start from
0. Then, we count 5 jumps to the
right. This shows the first addend.
From 5, we count 5 more jumps to
the right. This shows the second
addend.

8. This number line shows the addition
sentence 5+5=10.

9. Let’s Remember!
The process of combining or putting
things together is called addition.
The numbers that we add or put
together are called addends.
The answer in addition is called sum.
The symbol for addition is the plus
sign (+).
