2nd/3rd Grade - Place Value

Place Value is the 

VALUE (worth)

of each digit in a number.

​For now, let's talk about the HUNDREDS, TENS and ONES places.

​

​

​

H T O

A number stays the same, but it's VALUE depends on where it falls in a number.

H T O

                                                         2  4  5

​

​

2 HUNDREDS

  4 TENS

5 ONES

A single digit number or the number on the right....represents the ONES place.

​

9 or 19 

9 is the example.

The number to the left of the ONES place is in the TENS place. Here the TENS place is represented by the 4.

45

​10 sets of 1 make 10

​

​Ten sets of one make Ten

​

​1+1+1+1+1+1+1+1+1+1 = 10

​A 4 is always a 4, but its how much it is worth (its value) increases

to 40 when it lands in the Tens place of a number....like 45 or 145

For example...in the number 250

the VALUE of the 5 is really 50 as it lands in the TENS place. 

5x10=50

​or

10+10+10+10+10=50

To the left of TENS is HUNDREDS

375

​

3 HUNDREDS

7 TENS

5 ONES

​

​10 sets of 10 = 100

​

​Ten sets of ten equal one hundred

​

​10x10= 100

​10+10+10+10+10+10+10+10+10+10= 100
