2. Do Now:
1.) Take out your H.W. (if your take home quiz is done IF NOT IT IS DUE MONDAY), notebook, and packet
2.) Please answer in your notebook. What are things that you notice? What are things that you wonder?

3. Today’s Objective
I will be able to apply my knowledge of converting fractions to decimals
So I can calculate the sums and differences of decimals and apply this to real world scenarios.
I will demonstrate my understanding by verbally discussing with my partners and writing the solution to at least 1 real world and 2 mathematical problems with at least 80% accuracy NS.B.3

4. Math Language vocabulary
Sum,
difference
multi-digit numbers
decimals
Converting
rational numbers
addend, minuend
Subtrahend
Estimate
Rounding
mixed numbers
place value

5. DISCUSSION:
Can you describe circumstances when it would be easier to add and subtract mixed numbers by converting them to decimals first?
When fractions have large denominators, it would be difficult to find common denominators in order to add or subtract.

6. DISCUSSION:
Can you describe circumstances when it would be easier to add and subtract mixed numbers by converting them to decimals first?
When a problem is solved by regrouping, it may be easier to borrow from decimals than fractions.

7. DISCUSSION:
How can estimation be used to help solve addition and subtraction problems with rational numbers?
Using estimation can help predict reasonable answers.
It is a way to check to see if an answer is reasonable or not.

8. Notes in notebook:

9. Page 42
Step 1: Convert the mixed numbers into decimals.
Step 2: Round the addends to the nearest whole number Then, find the estimated sum.
=665
Step 3: Line up the addends appropriately using place value, and add.
32.3
32.3
664.94

10. Page 41 78.21-34.92 78-35 =43 78.21 -34.92 43.29 78.21 is the minuend
Step 1: Convert the mixed numbers into decimals.
34.92 is the subtrahend
Step 2: Round the minuend and subtrahend to the nearest whole number. Then, find the estimated difference.
78-35
=43
Step 3: Line up the minuend and subtrahend appropriately using place value, and subtract.
78.21
-34.92
43.29

11. Know you vocabulary:

12. most likely take longer to solve the problem
solve the problem using FRACTION
solve the problem using DECIMALS
ESTIMATE your answers before completing the problem.
most likely take longer to solve the problem
make more mistakes
using decimals made the problem easier to solve

13. topic.
How do you feel?

14. Problem set 1 (14 minutes)
Work in pairs or individually to complete pg. 42.
round the addends, minuends, and subtrahends to the nearest whole number in order to predict a reasonable answer.
Then solve to find the actual sum or difference.
**REMEMBER, it is not always easier to change fractions to decimals before finding the sum or difference.
