The document reviews place value and place names for decimal numbers. It discusses how to read and write numbers with decimals, such as four and five tenths or five and sixty-seven hundredths. It has students practice comparing the value of decimal numbers, such as determining whether 0.3 or 0.03 is greater, by representing them with place value counters on a place value chart.

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

3. CAN YOU NAME THE PLACE VALUE ON THE RIGHT OF THE DECIMAL POINT? 0

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

6. 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!")

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

8. TIME TO TRY!!! READ: 4.5 5.67 6.789 WRITE: Seven “and” twenty-five hundredths Twenty-two “and” five thousandths Four “and” five tenths Five “and” sixty-seven hundredths Six “and” seven hundred eighty- nine thousandths 7.25 22.005

10. 1/10’s 1/100’s Tenths Hundredths Decimal Point

11. CAN YOU GRAPH .3?

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

13. HOW TO GRAPH .3 (OR… “THREE TENTHS”)

14. HOW TO GRAPH .03 (OR… “THREE HUNDREDTHS”)

15. SO…. WHICH IS GREATER THAN? .3 .03

16. 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!

17. SO…. WHICH IS GREATER THAN? .6 .08

18. 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

19. Let’s check if your answers are correct!!!

20. GROUP 1 : WHICH IS GREATER THAN ? .56 .09

21. GROUP 2 : WHICH IS LESS THAN? .34 .09
