1. 5.M.NBT.03 Read, write, and compare decimals to thousandths.

2. Objective: I can read, write, and compare decimals to the thousandths.
Please say today’s objective

3. Essential Questions
What is a decimal? How does the place value of a number affect its value?
What is expanded notation? How is it applied using decimals?

4. SET
Think about what we talked about yesterday... how do we read, speak, and write decimals

5. A Quick Review A decimal is part of a whole.
A decimal represents a number less than one.
hundredths
whole number
thousandths
tenths

6. Tim and Moby Let’s review what decimals are:
andoperations/decimals/

7. Expanded notation Expanded notation can help with comparing decimals
Expanded notation takes a number and uses place value to determine each digits value.

8. Let’s try expanded notation with a few together
.45
0.582
6.359

9. Compare Decimals
Now that we know their place value, we can compare decimals. We can use concrete models or blocks to compare decimal values
0.6 is equal to 6/10
.60 is equal to 6/100

10. A Quick Review 0.4 (four tenths) = 0.40 (four hundredths)
Remember adding a place holder zero after the decimal point will not change the value of the number.
0.4 (four tenths) =
0.40 (four hundredths)

11. < > A Quick Review greater than less than
Do you remember what these signs mean?
>
greater than
<
less than
The sign “opens up” to or “eats” the larger number.

12. When comparing 2 decimals....
1. Line up the decimal points.
2. Add place holder zeros.
3. Work from left to right!

13. comparing Decimals
You need to know a decimals place value to compare them.

14. Practice Problems!
< , > or =
0.032 ____ 0.04

15. Practice Problemos! < , > or = < 0.032 ____ 0.04 0.032 0.04
1. Line up the decimal points.
2. Add place holder zeros.
3. Work from left to right!
<
0.032 ____ 0.04
0.032
0.04
4 is larger than 3, therefore 0.04 is larger than 0.032

16. Practice Problemos!
< , > or =
4.7 ____ 4.07

17. Practice Problemos! < , > or = > 4.7 ____ 4.07 4.7 4.07
1. Line up the decimal points.
2. Add place holder zeros.
3. Work from left to right!
>
4.7 ____ 4.07
4.7
4.07
7 is larger than 0, therefore 4.7 is larger than 4.07

18. Practice Problemos!
< , > or =
0.06 ____ 0.060

19. Practice Problemos! < , > or = = 0.06 ____ 0.060 0.06 0.060
1. Line up the decimal points.
2. Add place holder zeros.
3. Work from left to right! =
0.06 ____ 0.060
0.06
0.060
These numbers are equivalent

20. Let’s try a few
.45 _____ .54
.3 ____ .36
1.23 ____ 1.25

21. Closure Think about the steps you need to use to compare decimals...
On your slate write the steps you use
Repeat todays objective
