## Basics on the topicUsing Place Value to Add Two Digit Numbers (No Regouping)

How can you use place value to add two digit numbers? There are different ways to solve addition equations, one way is place value. You might already know that place value is the value of a number depending on where it is.

When adding using place value; * Start by representing the first addend, or, number on the place value chart using tens and ones. * Next, represent the second addend using tens and ones. * After that, add ALL of the blocks in the ones place together and write it under the chart. * Then, add ALL of the rods in the tens place together and write that number under the chart. * Finally, put the numbers together to find the answer under the line!

• ### How can we use place value to add two two digit numbers?

Hints

First we need to represent the first number, 32.

Next we need to represent the second number, 16. Now we will see both numbers represented in the place value table.

Solution

32 + 16 = 48

1. Represent the first number, 32.
2. Represent the second number, 16.
3. Add the ones, 2 + 6 = 8.
4. Add the tens, 3 + 1 = 4.
Now we can see our answer, 48.

• ### How many buttons does Mr Squeaks have?

Hints

We already have both of the numbers represented in the place value table, what is our next step?

Solution

23 + 54 = 77

• Add the ones blocks, 3 + 4 = 7
• Add the tens rods, 2 + 5 = 7
• Altogether we have 77
• ### How many metres has Mr Squeaks flown?

Hints

First, represent both of the numbers in a place value table.

Once you have represented the numbers, you can add the ones column.

Solution

Mr Squeaks flew 46 metres.

• Add the ones, 5 + 1 = 6
• Add the tens, 1 + 3 = 4
• Altogether that is 46 metres.

• ### Solve the addition problems using place value.

Hints

Start by representing each number in a place value table.

For example, when solving 22 + 17, your place value table could look like this.

Solution

22 + 17 = 39

We can see in the picture above that 22 and 17 have been represented in the place value table.

We can then add the ones, 2 + 7 = 9. Then add the tens, 2 + 1 = 3. Altogether that is 39.

__________________________________________

• 30 + 65 = 95
• 26 + 52 = 78
• 15 + 44 = 59
• ### How many parts does Imani have?

Hints

Both of the numbers have been represented in the table. Now we need to add the ones.

Next, we need to add the tens.

How many spare parts altogether?

Solution

13 + 16 = 29

• Add the ones blocks, 3 + 6 = 9
• Add the tens rods, 1 + 1 = 2
• Altogether that is 29 spare parts.
• ### Can you solve the problems?

Hints

Find the numbers you are adding together in each problem.

Create your own place value table and represent the numbers.

Solution

On Monday, the vets treated 34 cats and on Tuesday they treated 45 cats. How many cats did they treat across the two days? 79
