## Using Place Value to Subtract Without Regrouping– Introduction

Get ready because today we're going to practice using place value to subtract without regrouping. It’s a cool way to understand subtraction better using base ten blocks. Ready to begin? Let's go!

## What Does it Mean to Use Place Value to Subtract?

Using place value to subtract means breaking down numbers into tens and ones, and then subtracting each place value separately.

For example, if you have the number 33, you can represent it with three tens and three ones. This makes subtraction easier and more visual. It is also a very effective method when you do not need to regroup when subtracting. Let’s practice this with some fun problems!

What does using place value to subtract mean?
How can you represent the number 33 using place value?
Why do we use this method?

## Using Place Value to Subtract – Example

Let's solve a problem using place value to subtract:

Problem

What is 33 minus 12?

Solution

Follow these simple steps to find the solution.

Step Explanation Result
Represent 33 with base ten blocks Three tens and three ones 33
Cross off 2 ones and 1 ten Take away 2 ones from 3 ones and 1 ten from 3 tens
Count the remaining blocks Two tens and one ones 21

So, 33 minus 12 equals 21!

## Using Place Value to Subtract – Guided Practice

Let's try another problem together.

Problem

What is 58 minus 28?

How can you represent 58 using base ten blocks?
What should you cross off to subtract 28?
How many blocks are left?

So, 58 minus 28 equals 30!

## Using Place Value to Subtract – Application

Now, try solving this problem on your own:

Problem What is 83 minus 42?

How can you represent 83 using base ten blocks?
What should you cross off to subtract 42?
How many blocks are left?

So, 83 minus 42 equals 41!

## Using Place Value to Subtract – Examples

To help yourself in becoming fluent in using place value to subtract, have a look at some more examples and complete them by following the steps.

Problem Representation Cross Off Remaining Blocks Solution
33 - 12 Three tens, three ones Two ones, one ten Two tens, one one 21
58 - 28 Five tens, eight ones Eight ones, two tens Three tens 30
83 - 42 Eight tens, three ones Two ones, four tens Four tens, one one 41
64 - 32 Six tens, four ones Two ones, three tens Three tens, two ones 32

## Using Place Value to Subtract – Summary

Key Learnings from this Text:

• Using place value to subtract helps us understand subtraction by breaking numbers into tens and ones.

### TranscriptUsing Place Value to Subtract Two Digit Numbers (No Regrouping)—Let's Practice

Razzi says get these items ready (...) Because today we're going to practice... Using Place Value to Subtract (no regrouping). It's time to begin! Let's use base ten blocks to subtract. What is thirty-three minus twelve? We can represent thirty-three with three tens and three ones. Then cross off two ones and one ten... which leaves twenty-one. Did you also get twenty-one? Let's tackle the next problem! What is fifty-eight minus twenty-eight? We can represent fifty-eight with five tens and eight ones. Then cross off eight ones and two tens... which leaves thirty. Did you also get thirty? Let's try one more! What is eighty-three minus forty-two? We can represent eighty-three with eight tens and three ones. Then cross off two ones and four tens... which leaves forty-one. Did you also get forty-one? Razzi had so much fun practicing with you today! See you next time!

## Using Place Value to Subtract Two Digit Numbers (No Regrouping)—Let's Practice exercise

Would you like to apply the knowledge you’ve learned? You can review and practice it with the tasks for the video Using Place Value to Subtract Two Digit Numbers (No Regrouping)—Let's Practice.
• ### What is 67 subtract 42?

Hints

How many tens and ones in 42?

42 is made up of 4 tens and 2 ones. This is what you need to subtract from 67.

How much is left after 4 tens and 2 ones have been subtracted?

Solution

67 - 42 = 25

• ### What is 93 subtract 62?

Hints

Create a place value representation of 93.

There will be 9 tens and 3 ones.

In 62, there are 6 tens and 2 ones. Subtract this from 93.

Solution

93 - 62 = 31

• ### Can you find the answers to the subtraction problems?

Hints

Create your own place value grid and represent the larger number.

For example, if we were solving 98 - 55, we could create a place value grid like this.

We would then need to work out how many tens and ones in 55 and cross these off.

55 is made up of 5 tens and 5 ones. What is left is the answer.

Solution

98 - 55 = 43

We can see this represented in the image above.

______________________________________________________

• 77 - 36 = 41
• 86 - 53 = 33
• 64 - 32 = 32
• ### Solve the subtraction problems.

Hints

Represent the larger number with place value blocks.

You could draw them out with a pencil and paper.

Find out how many tens and ones the smaller number is made up of and cross these out.

You can use this image to help you to solve 62 - 41.

You can create something similar yourselves to solve the other problems.

Solution

21

• 62 - 41 = 21
• 76 - 55 = 21
• 48 - 27 = 21
