## Place Values - Ones, Tens, and Hundreds

#### Aligned To Common Core Standard:

**Grade 2 Base Ten** - 2.NBT.1

What are the place values (Ones, Tens, Hundreds)? The concept of place values is crucial to understand numbers and counting in mathematics. Every digit in math has a place value, and this value is determined by the position of the digit in a number. Understanding place values will help you write numbers in their expanded forms. Here is an example of an expanded form; 13,548 = 10,000 + 3,000 + 500 + 40 + 8. Taking the number 597, for example. Each digit in the number 597 holds a unique position and value. 5: The first digit in the number is five, which sits at the hundred's position. 9: The second digit in the number is 9, which sits at the ten's position. 7: The third digit in the number is 7, which sits at the unit's position. Hundred's Place The digit on the hundred's place tells the number of hundreds in a number. In the number 597 there are five hundreds; 100+100+100+100+100=500 Ten's Place The digit on the ten's place tells the number of tens in a number. In the number 597 there are nine tens; 10+10+10+10+10+10+10+10+10=90 Unit's Place The last digit in every number tells the number of ones in a number. In the number 597 there are seven ones; 1+1+1+1+1+1+1=7 The expanded form of 597 is; 597=500+90+7 With this large collection of worksheets students learn the concept and use of the first three place values.
