LET'S TAKE A MINUTE TO REMEMBER REGULAR PLACE VALUES AND PLACE NAMES FOR WHOLE NUMBER:

CAN YOU NAME THE PLACE VALUE ON THE RIGHT OF THE DECIMAL POINT?

LET'S LOOK AT THE PLACE VALUES IN NUMBERS... THIS IS HOW THESE GUYS GOT THEIR NAMES:

FIRST OF ALL, HOW DO YOU READ AND SAY REGULAR WHOLE NUMBERS?
HERE'S A LITTLE REVIEW:
"five hundred twenty-three"(Notice that we didn't say "and twenty-three!")

WE'RE SAVING THE BIG "AND" FOR THE DECIMAL POINT!

CAN YOU GRAPH .3?

Which is greater than?
0.3 or 0.03
Now that we can graph our decimal number, can you answer this?

LET’S TRY IT AGAIN!
Which is greater than?
.6 or .08
Group 1: Graph .6
Group 2: Graph .08
We will compare the graphs to figure out the answer!

TIME TO TEST!!
Use your counters and graphing paper!!!
GROUP 1
Which is greater than? .56 or .09
GROUP 2
Which is less than? .34 or .09
