## Compensation in Addition – Introduction

Get a piece of paper and a pencil ready because today we're going to practice something called compensation in addition. It’s a cool trick that makes adding numbers easier and faster. Ready to begin? Let's go!

## Understanding Compensation in Addition – Definition

Compensation in addition means adjusting one number to make the math easier, and then doing the opposite adjustment to the other number.

For example, if you add one to a number to make it easier, you subtract one from the other number to keep the balance. You will see that using number pairs to 10 will prove to be very helpful here! Let’s practice this with some fun problems!

## Compensation in Addition – Example

Let's solve a problem using compensation in addition:

Problem

If Mr. Squeaks has 29 blue flowers and 25 red ones, how many does he have in total?

Solution

Follow these simple steps to find the solution.

Step Explanation Result
Choose which number to make friendlier Let's make 29 friendlier
Add to the friendlier number Add 1 to 29 29 + 1 = 30
Adjust the other number Subtract 1 from 25 to keep the balance 25 - 1 = 24
Add the new numbers Add 30 and 24 30 + 24 = 54

So, Mr. Squeaks has 54 flowers in total!

## Compensation in Addition – Guided Practice

Let's try another problem together.

Problem

If Imani has 34 screws and 27 nails, how many are there all together?

So, Imani has 61 screws and nails in total!

## Compensation in Addition – Application

Now, try solving this problem on your own:

Problem If Mr. Squeaks has 58 red marshmallows and 32 blue ones, how many does he have in all?

What number can you make friendlier?
What is 60 + 30?

So, Mr. Squeaks has 90 marshmallows in total!

### Compensation in Addition – Examples

To be truly fluent in compensation in addition, have a look at some more examples and complete them by following the steps.

Problem Step 1: Make a Number Friendlier Step 2: Adjust the Other Number Step 3: Add the New Numbers Solution
29 + 25 Add 1 to 29 to make it 30 Subtract 1 from 25 to make it 24 30 + 24 54
34 + 27 Add 1 to 34 to make it 35 Subtract 1 from 27 to make it 26 35 + 26 61
58 + 32 Add 2 to 58 to make it 60 Subtract 2 from 32 to make it 30 60 + 30 90

### TranscriptCompensation in Addition — Let's Practice!

Razzi says get a piece of paper and a pencil ready (...) Because today we're going to practice... Compensation in addition! It's time to begin! Compensation is something given in return for something. Remember, when using compensation in addition, whatever you add to one number you MUST do the opposite for the other number. Let's practice! If Mr. Squeaks has twenty-nine blue flowers and twenty-five red ones, how many does he have in total? Start by choosing which number to make friendlier, or easier to add. Don't forget, whatever you do to one number you MUST do the opposite to the other. Here, you can take one from twenty-five and add it to twenty-nine to make thirty. Did you also get fifty-four? Let's tackle the next problem! If Imani has thirty-four screws and twenty-seven nails, how many are there all together? Don't forget, whatever you do to one number you MUST do the opposite to the other. Here, you can take one from twenty-seven and add it to thirty-four to make thirty-five. Did you also get sixty-one? Let's tackle the next problem! If Mr. Squeaks has fifty-eight red marshmallows and thirty-two blue ones, how many does he have in all? Don't forget, whatever you do to one number you MUST do the opposite to the other. Here, you can take two from thirty-two and add it to fifty-eight to make sixty. Did you also get ninety? Razzi had so much fun practicing with you today! See you next time!
