Adding the Integers 1-12

We work with fixed numbers to help improve our skills.

Number Lines

This is probably where I would start students when introducing this skill.

Math Facts

We focus solely on sums that should be mental math by the time you reach the primary level.

Visual Sums

This is the secondary progression for this skill. Attach values to objects.

The most basic of all these sheets.

Single and Double Digits

These can be memorized to make them automatic for you.

Regrouping with Addition

This helps students learn how find sums where you will need to regroup values.

The Commutative Property

This shows you that you can move integers around on each side of the equals sign to help you organize your thoughts.

Double Digits

This can result in a double carry often.

Double and Triple Digit

A great place to start working on carrying and regrouping values.

Adding 10s

You are given a set value and now they want you to pop on another ten.

Adding Triple Digit Numbers

This is a very common skill that carries into the middle levels.

4 to 4 Digit

Quadruple place value can be found in both numbers that we are summing together.

We learn to find the sum of large values by lining up the place values.

Adding Three Three-Digit Numbers

Most of these problems will be carrying values to thousands place.

Adding Large Numbers

This is something that you will regularly need to do for most jobs.

Adding Three Numbers

They are mostly composed of double- and triple-digit values, but there are three values to work with always.

Math Trail Puzzles

You need to determine where the trail leads and what values will follow in that path.

Missing Numbers

This is a great way to introduce algebra to students. There are fixed sums with missing values somewhere along the line.

Nothing changes here. Zero is the state of normal.

What is the Progression of Learning Addition?

Finding the sum of two integers is literally the origin of basic math. This is such a fundamental skill to function in any society these days. One thing teachers will often forget is that addition leads to a students’ impression on the topic of math itself. If they struggle, they find math too demanding and difficult. Help students have a great deal of success with this topic by stressing the importance of knowing your math facts. The use of flashcards will definitely make your job easier. The main thing that we stress here is to practice over and over. The more time you spend with these topics, the quicker and more accurate you will become.

Addition is a fundamental arithmetic skill that helps children develop a strong foundation for more complex mathematical concepts. Although this math operation is often one of the first skills taught to young children, it is essential to understand that the progression of learning addition varies depending on the child's abilities and needs.

What is It? Why Should You Learn?

Addition is one of the four basic operations in mathematics, along with subtraction, multiplication, and division. It is typically thought of as combining two numbers to get the third number, although there are other ways to think about it. For example, addition can be considered as putting things together or joining them together.

There are many reasons why you learn addition:

  • One reason is that it is a building block for other concepts in mathematics. For example, if you want to learn about multiplication, you must first understand addition.
  • Additionally, understanding this basic operation can help you with problem-solving in everyday life. For example, if you want to know how much money you have after you spend some, you need to be able to do an addition.
  • The addition is also an excellent way to practice your number sense. This is the ability to understand numbers and what they represent. When you add two numbers together, you are using your number sense to figure out what the answer should be.
  • This can be helpful in other areas of life, such as when you are shopping and need to figure out how much change you should get back.

The Process of Combining Two Groups of Objects

One of the earliest stages of learning addition is understanding that addition combines two groups of objects to find the total number of objects in both groups. This understanding is often first demonstrated through simple counting games and activities. As children develop a stronger understanding of addition, they will start to use addends, or the numbers that are being added together, to solve problems.

1. Addition on Number Line

Children will also begin to understand what addition looks like on a number line. This understanding is essential because it helps children visualize the addition process and see that addition can be done differently (e.g., starting at different points on the number line).

2. Use It to Solve Problem

As children understand addition, they will start to use addition to solve problems involving more than two numbers. This understanding is often first demonstrated through addition stories or word problems. In addition, children will begin to understand the commutative property of addition, which states that the order of the addends does not affect the sum. For example, 3 + 5 = 5 + 3.

3. Building Fluency

Eventually, children will develop fluency addition, which means they can solve problems quickly and accurately. This understanding is often demonstrated through addition facts or memorizing the answers to addition problems such as 2 + 2 = 4. In addition, children will begin to understand the associative property of addition, which states that the order of the numbers added does not affect the sum. For example, (2 + 3) + 4 = 2 + (3 + 4).

Wrapping Up

The progression of learning addition varies depending on the child's abilities and needs. However, children need to progress through each stage to develop a strong understanding of this fundamental arithmetic skill.
