within 50
Welcome to our Math Adventure! We will explore adding numbers. Get
ready to have fun. You will become an addition superstar!

2. What is Addition?
Putting things together
Addition means combining items.
Find out how many there are in total.
This is done by adding the numbers
together.
The plus sign
The plus sign (+) means "add". It
shows us that we need to add the
given numbers. For example, 2 + 2.
Example
2 apples + 1 apple = 3 apples. This
shows how addition works in real
life. Adding similar items together.

3. Adding with Pictures (Up to 10)
1 Count the objects
Count the objects in each
group. Then, count them all
together to find the total
amount.
2 Example 1
3 stars + 2 stars = ? Count the
stars. Then you can write the
correct number in the space.
3 Example 2
4 balls + 1 ball = ? You can add
the balls to get the total
number of balls. Add them all
together.

4. Adding on a Number Line (Up
to 20)
1 Start at first number
Start at the first number on the number line. This will be the
starting point for adding. Locate it first.
2 Jump forward
Jump forward the number of times indicated by the second
number. Each jump indicates adding one more.
3 Example
8 + 4 = ? Start at 8, then jump 4 spaces forward. This helps
visualize the addition. The answer will be 12.

5. Adding Using Your Fingers
(Up to 10)
Use your fingers
Use your fingers to help you
count. Fingers are a very
handy tool. You can use your
fingers any time you need.
Show the first number
Show the first number on
one hand. Show the second
number on the other hand.
For example, 2 fingers on
one hand and 3 fingers on
the other.
Count all fingers
Count all your fingers to find the answer. This makes it easy to see
the total. Use your hands to make the number.

6. Let's Practice! (Numbers up to
20)
Problem 1
Solve: 5 + 7 = ? Use the previous methods. Write down
the answer.
Problem 2
Solve: 9 + 3 = ? Use your fingers. Or try using the
number line method.
Problem 3
Solve: 6 + 8 = ? Take your time and add up the total
amount. You can even count objects.

7. Adding with Tens and Ones
(Introduction to Numbers up
to 50)
Tens
Numbers can be
broken down into
tens. 10 ones
combined make a
ten. It helps to think
about that fact.
Ones
Numbers can also be
broken down into
ones. Ones are the
individual numbers.
They are used to
make the larger
total.
Adding
When adding, add
the ones first, then
add the tens. This
makes it easier to
add bigger numbers.
Keep that in mind.

8. Adding with Tens (Numbers up to 50)
10 + 10 = 20 1
20 + 20 = 40
2
30 + 10 = 40
3

9. Real-World Addition (Up to 50)
Sticker Scenario
You have 20 stickers. Your friend gives you 15 more. How
many do you have? Add them up. What's the total
amount?
Birds in a tree
There are 32 birds in a tree. Then, 8 more fly in. How many
are there? Combine the birds. How many in total?

10. You're Addition Superstars!
Great job adding numbers. Keep practicing to become math wizards.
