If you have worked through the first four **Related Lessons** in the *Addition Strategies* series, you have learned four strategies to solve addition problems.

- What are the four strategies?

Can you remember all four addition strategies you learned in this series? Did you share your answer with your parent or teacher?

If you cannot remember all four, catch up with the **Related Lessons** in the right-hand sidebar.

Great job! Now, take a look at the list below to make sure you remembered all the fun and helpful strategies you have learned:

- drawing pictures
- writing tally marks
- using a number line
- counting on

These are all the strategies you have learned that can help you solve addition problems.

Now, it's time to review each strategy so you can use them in a snap!

First, you will review the *picture drawing* strategy. If you ever come across an addition problem that is too tricky to solve using mental math, you can draw pictures to help find the solution. Take a look at the problem below:

- What are the two numbers you see in this problem?

Tell your parent or teacher your answer.

That's right! There is a 4 and a 3 in this problem. Since this is not a word problem that asks for a certain object, we can draw circles to represent the numbers in the problem.

Take out a sheet of paper and a pencil. Once your materials are ready, solve the problem above by using pictures. Remember to draw above the number that matches the amount of pictures you drew.

Draw and solve the problem, then share your answers with your parent or teacher.

- Does your answer look like the one below?

The second strategy you used to solve addition problems was writing *tally marks*. This is very similar to the picture drawing strategy, except you draw tally marks instead. Try drawing tally marks to solve the problem below:

Share your answer with your parent or teacher.

- Does your answer look like the one below?

Fantastic!

The third strategy you learned involved using a *number line* to solve addition problems. Draw a number line like the one below:

Look at the example below of the addition problem being solved.

- Do you remember how to use this strategy?

Don't forget your hopping frogs!

Use this strategy to solve the problem below.

Solve the problem on the number line you drew, then share your answer with your parent or teacher.

- Does your answer look like the answer below?

Excellent work!

The fourth strategy you learned was the *counting on* strategy. You will need your fingers for this strategy; hopefully, you didn't lose them!

This strategy is meant to be used with numbers smaller than ten. For example, if you were solving the problem, 2 + 2, first you would hold up two fingers, then you would hold up two more fingers. You would count all of the fingers you held up, and the number of all your fingers together is your answer.

Try counting on with your fingers to solve the problem below. Share your answer with your parent or teacher:

- Did you solve the problem and find the answer below?

Great work!

- Was it encouraging to review all of the addition strategies you learned?

Move on to the *Got It?* section to practice using all of the strategies you have learned.
