Solve Using Your Place Value Chart And Place Value Disks
Introduction
Mathematics is one of the essential subjects that we learn in school. It helps us in our daily lives, and that is why it is crucial to understand its concepts. One of the essential concepts that we need to learn in mathematics is the place value system. The place value system is an essential part of mathematics, and it is used in various mathematical operations. In this article, we will discuss how to solve mathematical problems using your place value chart and place value disks.
What is a Place Value Chart?
A place value chart is a chart that represents the place value system. The place value system is a system that uses the position of digits in a number to determine the value of the number. The place value chart has columns that represent the different place values in a number. The columns are usually labeled with the place value names such as ones, tens, hundreds, thousands, ten thousands, hundred thousands, and so on.
What are Place Value Disks?
Place value disks are physical disks that represent the place value system. They are usually used in classrooms to teach students how to understand the place value system. The disks come in different colors, and each color represents a different place value. For example, the green disk represents ones, the blue disk represents tens, the red disk represents hundreds, and so on.
How to Solve Using Your Place Value Chart and Place Value Disks
Now that we know what a place value chart and place value disks are let us look at how to solve mathematical problems using them. When solving problems using the place value system, we need to understand the value of each digit in a number. For example, in the number 274, the digit 7 is in the tens place, and its value is 7 x 10 = 70.
Let us look at an example of how to solve a problem using the place value system. Suppose we want to add 245 and 173. We can use our place value chart and place value disks to solve this problem. First, we write the numbers in our place value chart.
Next, we use our place value disks to represent the numbers. We use green disks to represent the ones, blue disks to represent the tens, and red disks to represent the hundreds.
Now that we have represented the numbers using our place value disks, we can add them by starting with the ones place. We have 5 ones and 3 ones, which gives us 8 ones. Next, we move to the tens place. We have 4 tens and 7 tens, which gives us 11 tens. We can represent 11 tens as 1 hundred and 1 ten. Finally, we move to the hundreds place. We have 2 hundreds and 1 hundred, which gives us 3 hundreds. Therefore, the answer is 418.
Conclusion
The place value system is an essential part of mathematics, and it is used in various mathematical operations. Understanding the place value system is crucial in solving mathematical problems. Using your place value chart and place value disks can help you understand the place value system better and solve mathematical problems more easily. So, next time you encounter a mathematical problem, remember to use your place value chart and place value disks.
