2. ACTIVATOR (December 4, 2014) :
Take out your H.W & notebook.
In notebook, answer this:
“Use estimation to determine if 8,580 ÷ 78 has a quotient in the 10s, 100s, or 1000s.”

3. December 4, 2014
Day D
SWBAT connect estimation with place value in order to create and compute (using the standard algorithm) decimal division problems on pages
We will show what we know when we successfully complete our ticket to go.

5. Estimate this quotient: 𝟖,085 ÷ 33
December 4, 2014
Day D
Example 1 (pg. 46)
Estimate this quotient:
𝟖,085 ÷ 33
Many possible answers: 8,000 ÷ 30 8,000 ÷ 35 8,100 ÷ 30 8,100 ÷ 35
Best option: 𝟖,100 ÷ 30 = 270
“3 is not a factor of 8, but it is a factor of 81”

6. Example 1 (pg. 46) December 4, 2014 Day D
Model to show the division of 𝟖, 𝟎𝟖𝟓 by 33.

7. December 4, 2014
Day D
Example 1 (pg. 46)
𝟖,085 ÷ 33= 245

8. 1500 ÷ 30 = 50 Example 2 (pg. 47) December 4, 2014 Day D
Use estimation and the standard algorithms to divide ÷ 27
1500 ÷ 30 = 50
In the algorithm, we can show that there are fifty 27’s by placing a 5 over the tens place. We know that 5 tens is 50. This is really showing that 151 tens ÷ 27 = 5 tens.

9. Example 2 (pg. 47) December 3, 2014 Day C
I would multiply 50 × 27, which is 1,350. Then, I would subtract 1,350 from 1,512.
Same as the algorithm:
