# Addition by Partners of Tens Strategy

## What is the Mental Math Addition by Partners of Tens Strategy Making Tens?

Make a Ten is a Mental Math Addition by Partners of Tens Strategy where students use the number combinations that make ten to form connections and relationships to other facts. First, students must learn the number combinations that make 10. Then, they can confidently use those combinations.

## How to do Mental Math Addition

• Add the digits in the tens column together and remember this result.
• Add the digits in the units column together.
• If this result is larger than ten then add one to your tens column answer from before.
• The units column of the units column result is the units digit of your answer.

## What is the Jump Strategy For Addition Mental Strategies?

Jump strategy

Some students add increments of tens or ones, while others add or subtract multiples of tens then ones. For example, adding 46 + 23 using the jump strategy might look like this: add two lots of ten to 46: 46 + 10 = 56, then 56 + 10 = 66. add the remaining 3: 66 + 3 = 69.

## What is Mental Math Addition by Partners of Tens Strategy Called?

Mental math Addition by partners of tens strategy is the ability to perform mathematical calculations in your mind. It is also known as mental arithmetic, mental calculation, quick math, fast math, or doing math in your head. In German, it is known as Kopfrechnen, which translates into English as “head calculation”.

## Can you Think of Different Strategies To Add Large Numbers Mentally?

Either mentally or with a pencil, go down the vertical column of numbers you need to add, and group them into units of 10. For instance, in the vertical column 9 + 3 + 7 + 2 + 4 + 7 + 4 + 1, you can find three units of 10 (3 + 7, 2 + 4 + 4, 9 + 1) with 7 left. Therefore, your sum of this single column will be 37.

## What is the Concept of Addition?

Addition in math is a process of combining two or more numbers. Addends are the numbers being added, and the result or the final answer we get after the process is called the sum. It is one of the essential mathematical functions we use in our everyday activities.
What is an example of a mental computation strategy?

## COUNTING ON & COUNTING BACK

For example, in order to calculate 11 + 4 one could simply count on four from 11, i.e. 12, 13, 14, 15 (counting on in 1s). In order to calculate 19 – 3 one could count back three from 19, i.e. 18, 17, 16 (counting back in 1s).

## “Mental Math Addition Using Partners of Tens Strategy”

The partners of tens strategy is a mental math technique used to quickly add numbers by breaking them down into groups of ten. This method is particularly useful for adding numbers that are close to multiples of ten. Here’s how it works:

1. Identify the numbers you want to add.
2. Look for pairs of numbers that, when combined, make ten. These are your “partners of tens.” For example, 3 and 7 make ten, or 6 and 4 make ten.
3. Add these pairs of numbers together first.
4. Then, add any remaining numbers that don’t make ten to the sum from step 3.

### Let’s take an example:

Problem: 38 + 56

1. Identify the numbers: 38 and 56.
2. Find the partners of tens: 3 and 7 (from 38) and 6 and 4 (from 56).
3. Add the partners of tens together: 3 + 7 = 10 and 6 + 4 = 10.
4. Now, add the two results from step 3 together: 10 + 10 = 20.
5. Finally, add the remaining numbers: 20 + 8 = 28.

So, 38 + 56 = 94 using the partners of tens strategy. This method can make mental addition faster and more manageable, especially when dealing with larger numbers.
