How would you solve the problem below?

12 + 5 =

Addition problems can be tricky when there are two-digit numbers.

Think of a time you had to solve a hard addition problem. What steps did you use? How did you find the answers? Share your steps with your parent or teacher.

One great move to use when solving addition problems up to 20 is to draw simple pictures. For example, you could draw 12 circles for the problem below. Then 5 more circles. If you count all of the circles, you will find the answer to 12 plus 5. Look at the problem below. What is the answer to this problem?

Did you say 17 is the answer to the problem? Great work! You will be applying this strategy to solving addition word problems. Take a look at the problem below. What is missing?

  • Bob put ____ cookies on the table. Then he put ____ more cookies on the table. How many cookies are on the table?

Did you notice there weren't any numbers in the problem? You can't solve an addition problem without any numbers! The first thing you should always look for is the numbers.

Now take a look at the problem below. Can you find the two important numbers in this problem?

  • Bob put 7 cookies on the table. Then, he put 4 more cookies on the table. How many cookies are on the table?

Did you say 7 and 4 are the important numbers in this problem?

Great work! There is another part of addition problems you need to look for. This is the part that tells you what you need to do to solve the problem.

  • Bob put 7 cookies on the table. Then, he put 4 more cookies on the table. How many cookies are on the table?

At the end of the problem, there is a question that asks how many cookies there are on the table. This question tells you that you need to add all of the cookies together. Can you add 7 plus 4? Use the picture below to help you:

If you count all the cookies together, you will find your answer. The answer is 11. There are 11 cookies on the table. Did you find this answer? Fantastic!
