Basics on the topic Using 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!

Transcript Using Place Value to Add Two Digit Numbers (No Regouping)

"Hmm, something is not adding up for my plane." "We should run the calculations using place value to make sure we did everything correctly." "Adding using place value?" We can help our friends learn about 'Using Place Value to Add Two-Digit Numbers (no regrouping) to solve their problem. 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 one's 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! Let's take a look at Mr. Squeaks and Imani's first equation to learn more. They are adding twenty plus twelve for the wood they will use. What is twenty plus twelve? Start by representing the first addend using tens and ones. We can represent twenty with two tens and zero ones. Next, represent the second addend using tens and ones. We can represent twelve with one ten and two ones. After that, we need to add all of the blocks in the ones place. Zero plus two equals two. Then, we need to add all of the tens together. Two plus one equals three. Finally, we can see our answer under the line, thirty-two! Imani is adding thirty-two square bolts and sixteen circular bolts together. What is thirty-two plus sixteen? Start by representing the first addend, thirty-two. Thirty-two can be represented by three tens and two ones. Next, represent the second addend, sixteen. Sixteen can be represented by one ten and six ones. After that, we can add all of the ones blocks together. What is two plus six? Eight! Then, we can add all of the tens rods together. What is three plus one? Four! Finally, put the numbers under the line together to find the answer. There are forty-eight bolts for the plane. Mr. Squeaks is adding forty-three purple rods and twenty-four pink rods to his plane. What is forty-three plus twenty-four? We can use place value one last time! Remember, start by representing the first addend using tens and ones. Next, represent the second addend. Then, add all of the ones blocks together and then all of the tens rods together. Finally, put the numbers under the line together to find the answer. How many rods does Mr. Squeaks have in total? Sixty-seven! Before we see Mr. Squeaks fly, let's remember. When adding using place value, start by representing your first addend using tens and ones. Then, represent your second addend using tens and ones. Next, add all of the ones blocks together. After that, add all of the tens rods together. Finally, put the numbers under the line together to find the answer! : "I'm flying, Imani, flying!" "Sure you are!"
