We start working on sums with smaller integers with these worksheets.

This is a natural progression from math addition facts. Students for the first time now have to think critically for math. In this section of worksheets they will be presented will familiar numbers being summed with another familiar number, but it ends in an unfamiliar larger number. Also you move down the page you will see that we grouped sums by addends. This should help you if the top half worksheets are giving the students some trouble. We stretch this section from single digits to double digits. We end off at the number twelve. There are also no zero sums on these worksheets. You will notice that we start off with single digit addition which doesn't seem to follow a pattern of any kind. The paced integers will follow those starting worksheets.

How to Practice Adding the Integers 1-12

Are you struggling with adding the integers 1-12? Maybe you're finding it hard to remember the order of the numbers. Or maybe you just need a little practice to get your speed up.

In any case, this article will help you! Here, we'll give you tips on practicing and improving your skills in adding the integers 1-12.

What are Integers?

Integers are numbers that fall between positive and negative numbers on a number line. They include the whole numbers (1, 2, 3, etc.) and their opposites, the negative numbers (-1, -2, -3, etc.). Adding integers can be tricky, but it can become easier with practice.

Ways to Practice Adding Integers

Number Lines

One way to practice adding the integers 1-12 is to use a number line. You'll need a piece of paper and a pencil to do this. First, draw a line on your paper. Then, label the numbers 1-12 along the line. Once you have your number line set up, start at the number 1 and count up to 12.

As you count, make sure to write down the numbers in order. After you reach 12, stop and check your work. Make sure that you have all of the numbers in order and that you haven't missed any.

If you find that you made a mistake, don't worry! Just erase it and try again.

Number Charts

Use a number chart. To set up a number chart, you'll need a piece of paper and a pencil. On your paper, draw a table with 12 rows and 12 columns. Then, label the numbers 1-12 along the top row and down the first column.

Once your chart is set up, start filling in the rest of the numbers. To do this, add the numbers in each row and column until you've filled all the boxes. After you're finished, check your work to ensure you haven't made any mistakes.


Use addition flashcards. You can make your flashcards by writing the numbers 1-12 on pieces of paper or index cards. Once you have your flashcards made, shuffle them and lay them out in a row. Pick up the first card and say the number out loud.

Then, look at the other cards. Find the number that adds up to 12 with the number on the first card. For example, if the number on the first card is 5, you would look for the number 7 on one of the other cards.

Once you've found the answer, say it aloud, and then put the two cards together. Continue until you've gone through all of the cards.

Integers Mazes

It is another way to practice adding the integers from 1 to 12. In this activity, students will solve addition problems and color their path from start to finish. This no-prep activity can be used as independent work, in math centers, or as homework.


This is a classic game that can be used to review adding integers. You will need to print out bingo cards for each student in your class. To make the bingo cards, you can use this bingo card generator.

To play the game, students will take turns picking a number straight out of the bag and calling it out. The rest of the students will look for that number on their bingo card and mark it off if they have it. The first student to get five in a row ( horizontally, vertically, or diagonally) wins the game!

If you get stuck, don't worry! Just go back and try again.

Final Words

Practicing adding the integers 1-12 is important if you want to improve your math skills. Using a number line, number chart, addition flashcards, etc., gives you a great opportunity to practice and improve your abilities.
